Electric ball valve Danfoss. An overview of the varieties of danfoss ball valves. Design features of reinforcement

Danfoss is one of the most innovative manufacturers in the world plumbing equipment. Today, the brand's list of products includes about 350 products and solutions for home and industry. One of the most popular products for organizing pipelines is the Danfoss steel ball valve.

Classification of Danfoss Steel Ball Valves

Ball valves are required to shut off the flow of the medium flowing through the pipeline or to release the medium from the pipeline during drainage. All Danfoss ball valves are connected to the pipeline by flange connection on both sides or by welding, a handle is used as an external opening / closing lever.

All steel Danfoss cranes are produced in the JiP line, which is divided into two series: Standard and Premium. In the first case, the valves are designed for a pressure of 16 bar, in the second - over 16 bar.

JiP Standart

JiP Standart are 2 main types of valves with welded or flanged connection. In the first case, the crane is called JiP Standard FF, in the second - JiP Standard WW. Both solutions withstand pressures up to 16 bar, regardless of the flow diameter, which can be up to 150 mm. Cranes of this series are on-off, because work in two modes: "open" and "closed".

JiP Premium

JiP Premium is 6 different modifications of cranes with different drives, which can be either manual (two-position handle) or geared. Varieties of JiP Premium:

• JIP/G-FF flange type with gear drive;
• JIP-FF flange type, manual drive - two-position handle;
• JIP-WW butt weld, two position handle;
• JIP / G-WW for welding, drive - gearbox;
• JIP-FF flange, under the drive;
• JIP-WW flange, under the drive.

AUMA electric actuator for Danfoss JiP ball valves is an AUMA industrial electric actuator, which is designed for Danfoss series shut-off steel ball valves. The AUMA actuator is manufactured German company"Armaturen Und MaschinenAntriebe", which is the world's leading manufacturer of electric drives for automated control pipeline shut-off valves. AUMA actuators are different a high degree resistance to vibration and voltage drops, have an increased degree of protection IP67, and can operate at critical temperatures from -60 °C to +80 °C. They are also finished with two coats of silver gray powder coating, the first coat based on epoxy resin, the second layer based on polyurethane. This coating provides protection of the device from chemicals, high resistance to corrosion and weathering.

The AUMA electric actuator for Danfoss JiP cranes makes it possible to automate the control of shut-off valves in the OPEN-CLOSE mode, including auto mode regulation. To automate the control of Danfoss shut-off ball valves, AUMA electric actuators of two types are used: part-turn actuators of the SQ series and multi-turn actuators of the SA series. Part-turn actuators SQ are used for ball valves with diameters from 65 mm to 250 mm, and multi-turn actuators SA for ball valves with large diameters from 300 mm to 600 mm. The AUMA electric actuator for Danfoss JiP cranes can be supplied both as a basic package and as a set with the AUMA MATIC AM 01.1 control unit.

Functional purpose and range of products

The ball valve is an alternative to oversized and gate valves designed for use in domestic pipelines. Due to the design features, the crane has greater reliability, durability and.

The functional task of the crane is to shut off the flow of the medium transported by the pipeline, which is necessary when installing branched highways. By installing shut-off valves, you get a system divided into several isolated sections, which greatly simplifies its operation. If necessary, it is possible to block one of the sections by cutting it off from the central circuit, which will avoid an emergency or carry out pipe repairs if it occurs.

The range of Dafnoss also includes. The company supplies valves different types- made of brass, aluminum or plastic. Also, products differ depending on the installation method, according to which threaded, flanged and welded valves are distinguished.

Dafnoss is a Danish company, one of the world's leading manufacturers of sanitary ware. The company has been present on the domestic market for more than 20 years, during which the quality of its products has been repeatedly confirmed in practice.

Design features of reinforcement

Cranes from Daphnoss, the most common Jip and FF series have a similar design. The constituent elements of these products are:

• case (metal or plastic);
• ball-shaped locking element (the ball is made of brass or stainless alloy and is additionally processed diamond polished, due to which a smooth operation of the shutter and the absence of noise of the medium transported through pipelines are achieved);
• sealing elements made of rubber or synthetic rubber (EPDM) located on the stem and at the junction of the valve with pipes;
• drive - a handle of the "butterfly" type or a classic rotary lever, also the fittings can be equipped with an electric drive;
• a stem connecting the valve to the actuator, and a fixing nut.

The ball valve is used as It can operate in three positions - open (the size of the through hole is maximum), partially open (if necessary, set a certain throughput of the pipeline) and closed (the locking element closes the hole, ensuring complete shut-off tightness).

In the Jip and LD series, valve models are presented in two designs - for threaded and flanged connections to the pipeline. For domestic use, it is recommended to use threaded structures, since their installation can be performed in as soon as possible, without using special tools(you only need an adjustable wrench or open-end wrench).

The company sells both full bore and reducing (standard bore) cranes. The differences between them are that in full bore valves the diameter of the through hole in the shutoff element (ball) corresponds to the cross section of the pipeline. Such designs provide minimal hydraulic losses circulating medium with the shut-off valve fully open.

In reduction analogs, the shut-off ball has a through hole, one standard size smaller in diameter than the pipe size. Such structures are installed in domestic pipelines, where partial pressure loss is not critical.

Overview of the range of Daphnoss cranes

The Danish company supplies the market with several lines of ball valves that differ design, operational characteristics and price:

• Dafnoss JIP-FF;
• Dafnoss LD-FF;
• Dafnoss Eagle;
• Dafnoss BVR.

Let's consider each of the varieties in more detail.

Jip-FF series products

The Jip-FF line includes flanged valves, which is indicated by the marking FF. The fittings are designed for installation on pipelines transporting liquid working medium - water supply systems, heating systems and industrial lines.

The structures are made in an all-welded metal case made of carbon steel grade ST-37. Product specifications are as follows:

• standard sizes (diameter of pipes on which fittings can be installed) - 15-200 mm;
• throughput: 12-2300 m 3 / h;
• nominal operating pressure: 30-40 bar;
• temperature range: 0-190 degrees.

Jip-FF valves have a stainless steel shut off mechanism and are equipped with pressure springs to ensure maximum flow tightness.

Valve Series LD-FF

The model range of LD fittings is also designed for flange connection, however, valves have analogues for installation by welding (marked LD-WW) and coupling docking (LD-II).

Unlike the JIP series, the LD fittings are characterized by a simpler design (there are no clamping springs) and lower operational capabilities, as evidenced by the technical characteristics of the products:

• throughput: 10-1700 m 3 /h;
• nominal working pressure - up to 30 bar;
• operating temperature - up to 150 degrees.

The fittings of the LD line can be full bore or reducing. Fluoroplastic is used as sealing elements, the locking ball is made of stainless steel. Product sizes - 15-200 mm.

Eagle Crane Series

The most demanded series of fixtures for domestic use are Eagle faucets, made of brass covered with a protective nickel-plated coating. The Eegle line has replaced the old generation of Dafnoss Techno A cranes.

Products are produced for pipes diameter 15-100 mm. Specifications are as follows:

• throughput: 16-1350 m 3 / h;
• working pressure: 15-30 bar;
• operating temperature - up to 120 degrees.

Sealing fittings are made of nitrile (NBR) and fluoroplastic (PTFE), the locking ball is made of chrome-plated brass. Docking from pipelines is carried out at the expense of threaded connection, the thread on the fitting can be internal or external. Eagle taps are also produced, equipped with a pressure stabilization system - outlet for bleeding air from the pipeline, which is necessary when operating radiator heating systems.

In general, Danfoss Eaegle series cranes are the best option stop valves for picking plastic pipelines from PVC, HDPE, PE and.

Motorized valve series X3555 and X3888

Designed for installation on pipelines transporting water, gas and vaporous substances, the temperature of which does not exceed 80 degrees. Such designs, in comparison with mechanical counterparts, have a lower working pressure - up to 6 bar.

The case of the electric drive is protected from moisture according to the IP65 standard. Sensor built into the faucet thermal resistance, which signals an increase in temperature above the permissible maximum. The drive is powered by a 230 V power supply. The design is equipped with a redundant manual drive to shut off the water supply in case of emergency.

Danfoss electric actuators have four limit switches - you get the ability to program 4 positions of the locking assembly to adjust the required bandwidth pipeline. The only limitation on the use of such devices is relatively big size housing of the electric drive, which does not allow installing fittings in pipeline sections located in confined spaces.
