German GSR solenoid valve
$120.71
The working principle of the German GSR solenoid valve is as follows: It combines direct-acting and pilot-operated principles. When there is no pressure difference between the inlet and outlet, upon energization, the electromagnetic force directly lifts the pilot valve and the main valve closing element sequentially, opening the valve. When the inlet and outlet reach the starting pressure difference, upon energization, the electromagnetic force actuates the pilot valve, causing the pressure in the lower chamber of the main valve to rise and the pressure in the upper chamber to fall, thus using the pressure difference to push the main valve open. When de-energized, the pilot valve uses spring force or medium pressure to push the closing element downward, closing the valve.

German GSR Solenoid Valves
Brand Introduction:
Founded in 1971, GSR GmbH specializes in the development and manufacturing of solenoid valves, pneumatic valves, and electric valves. In addition to over 2000 standard products, they also offer high-temperature (350℃), high-pressure (350bar), and large-diameter (DN400) solenoid valves and pneumatic/electric valves; furthermore, they can provide customized designs based on user requirements. GSR electric valves, GSR solenoid valves, GSR pneumatic valves, GSR regulating valves, and GSR pneumatic solenoid valves from Germany are used in various medium-temperature, high-temperature, normal-pressure, and high-pressure applications. They are suitable for the automatic control of pipelines handling medium- and high-temperature hot water, high-temperature steam, saturated steam, superheated steam, and heat transfer oil. GSR products are widely used in kiln equipment, drying equipment, petrochemicals, biopharmaceuticals, HVAC, electroplating and coating, rubber and plastics machinery, food and beverage, papermaking, printing and dyeing, and power and mining industries. They are essential products for automation control engineering, project upgrades, and equipment matching.
Principle: When energized, the electromagnetic coil generates electromagnetic force that lifts the closing element from the valve seat, opening the valve. When de-energized, the electromagnetic force disappears, and the spring presses the closing element back onto the valve seat, closing the valve.
Features: Can operate normally under vacuum, negative pressure, and zero pressure, but the nominal diameter is generally no more than 25mm.
Step-by-step direct-acting solenoid valve
Principle: It combines direct-acting and pilot-operated principles. When there is no pressure difference between the inlet and outlet, upon energization, the electromagnetic force directly lifts the pilot valve and the main valve's closing element sequentially, opening the valve. When the inlet and outlet reach the starting pressure difference, upon energization, the electromagnetic force actuates the pilot valve, increasing the pressure in the lower chamber of the main valve and decreasing the pressure in the upper chamber, thus using the pressure difference to push the main valve open. When de-energized, the pilot valve uses spring force or medium pressure to push the closing element downwards, closing the valve.
Features: It can operate at zero pressure difference, vacuum, or high pressure, but requires higher power and must be installed horizontally.
The working principle of the German GSR direct-acting solenoid valve:
The GSR solenoid valve has a sealed chamber with through-holes at different positions, each connecting to a different oil pipe. Inside the chamber is a piston, flanked by two electromagnets. When the coil of one electromagnet is energized, the valve body is attracted to that side. By controlling the movement of the valve body, different drain holes are opened or closed. The inlet hole is always open, allowing hydraulic oil to enter the different drain pipes. The oil pressure then pushes the piston in the cylinder, which in turn moves the piston rod, which in turn drives the mechanical device. Thus, controlling the flow of current to the electromagnets controls the mechanical movement.
GSR Solenoid Valves (Germany)
Based on their operating principle, they are divided into three main categories:
GSR Pilot-Operated Solenoid Valves (Germany)
Principle: When energized, electromagnetic force opens the pilot orifice, causing a rapid drop in pressure in the upper chamber. This creates a pressure differential around the closing element, with lower pressure at the top and higher pressure at the bottom. The fluid pressure pushes the closing element upward, opening the valve. When de-energized, spring force closes the pilot orifice. The inlet pressure quickly passes through the bypass orifice, creating a pressure differential around the closing element, with lower pressure at the bottom and higher pressure at the top. The fluid pressure pushes the closing element downward, closing the valve.
GSR GmbH, founded in 1971 and headquartered in Bielefeld, Germany, is a multinational group specializing in the design, production, and sales of solenoid valves, pneumatic valves, and other related products.
GSR electric valves can be continuously energized for extended periods in special applications, employing all-metal seals. The medium fluid temperature can reach 450°C. Liquids, steam, condensate, and oils can be mixed, further expanding the application range of the solenoid valves. Different media require targeted sealing, enhancing the overall performance of the solenoid valve.
