Germany GSR electric valve, GSR solenoid valve, GSR gas control valve, GSR regulating valve, GSR pneumatic solenoid valve for a variety of medium temperature, high temperature, atmospheric pressure, high pressure occasions, suitable for medium high temperature hot water, high temperature steam, saturated steam, superheated steam and thermal oil pipeline automatic control; German GSR company products are widely used in kiln equipment, drying equipment, petrochemical, biopharmaceutical, HVAC, electroplating coating, rubber machinery, food and beverage, paper making, printing and dyeing and power mining and other industries, is the automation control engineering, project transformation and equipment supporting choice products. Special occasions sustainable power for a long time, the use of all-metal seal, medium fluid temperature up to 450℃. Liquid, steam and condensate water, oil products can be mixed to improve the use of the solenoid valve range of different media, the use of targeted seal, more improve the rationality of the solenoid valve. The use of novel and ingenious spool structure and installation of heat dissipation device, so that the structure is more compact, the weight is one third of similar products, the use of stainless steel piston structure, spool wear can be
