GSR solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems. Used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system. Common types include check valves, safety valves, directional control valves, and speed control valves.

GSR Solenoid Valve Working Principle

The solenoid valve contains 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. Controlling the movement of the valve body opens or closes different drain holes. The inlet hole is always open, allowing hydraulic oil to enter 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 current to the electromagnets controls the mechanical movement.

GSR Solenoid Valve Selection Criteria:

1. Select the solenoid valve based on pipeline parameters: nominal diameter (DN) and connection type.

1) Determine the nominal diameter (DN) based on the inner diameter of the pipeline or flow requirements.

2) For connection type, generally, >DN50 requires a flange connection; ≤DN50 can be freely selected according to user needs.

2. Selection of Solenoid Valves Based on Fluid Parameters: Material and Temperature Group

1) Corrosive fluids: Corrosion-resistant solenoid valves and all-stainless steel valves are recommended; Ultra-clean edible fluids: Food-grade stainless steel solenoid valves are recommended;

2) High-temperature fluids: Solenoid valves made with high-temperature resistant electrical and sealing materials should be selected, and piston-type valves are preferred;

3) Fluid state: Fluids can be gaseous, liquid, or mixed, especially for diameters greater than DN25, which must be clearly distinguished;

4) Fluid viscosity: Generally, any viscosity can be selected below 50 cSt. If this value is exceeded, a high-viscosity solenoid valve should be selected.

3. Selecting Solenoid Valves Based on Pressure Parameters: Principle and Structure

1) Nominal Pressure: This parameter has the same meaning as other general-purpose valves, determined by the nominal pressure of the pipeline.

2) Working Pressure: If the working pressure is low, a direct-acting or step-direct-acting principle must be selected. For a minimum working pressure difference of 0.04 MPa, direct-acting, step-direct-acting, and pilot-operated valves can all be selected.

4. Electrical Selection: AC220V and DC24V voltage specifications should be prioritized for convenience.

5. Selecting Based on Continuous Working Time: Normally Closed, Normally Open, or Continuously Energized

1) When the solenoid valve needs to be open for a long time, and the continuous time is longer than the closing time, a normally open type should be selected.

2) If the opening time is short or the opening and closing times are infrequent, a normally closed type should be selected.

3) However, for some safety protection applications, such as furnace and kiln flame monitoring, normally open valves cannot be selected; a continuously energized type should be chosen. 6. Auxiliary functions can be selected according to environmental requirements: explosion-proof, check valve, manual operation, waterproof mist, water spray, and submersible.

German GSR solenoid valves are used in various medium-temperature, high-temperature, normal-pressure, and high-pressure applications. They are suitable for automatic control of pipelines carrying medium- and high-temperature hot water, high-temperature steam, saturated steam, superheated steam, and heat transfer oil. They 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 renovation, and equipment matching. In special applications, they can be continuously powered for extended periods, employing all-metal seals, and can handle media temperatures up to 450℃. Liquids, steam, condensate, and oils can be mixed, further expanding the solenoid valve's application range. Different media require targeted sealing, enhancing the valve's versatility. The novel and ingenious valve core structure and heat dissipation device result in a more compact structure, weighing one-third of similar products. The stainless steel piston structure automatically compensates for valve core wear, further improving the solenoid valve's lifespan and reliability, allowing for continuous and frequent operation. The maximum media pressure can reach 45 MPa. Our main products include direct-acting solenoid valves, pilot-operated solenoid valves, forced-pilot solenoid valves, pneumatic valves, and electric valves. In addition to standard products, we also offer custom-designed non-standard products. We maintain a large inventory; please inquire for more information.
