Description

Sanzhou valve provides the control valve, such as pneumatic single seat control valve, electric single seat control valve, double seat control valve, sleeve type control valve, angle style control valve, three way control valve, butterfly style control valve, V-type ball style control valve, O-type ball style control valve, three shut-off valve, direct role of Self-pressure, temperature control valve, etc. They are more than **0 species, and more than **0 specifications. Detailed Product Description: Electric pneumatic single seat (sleeve) control valve is made up of lower resistance through single seat valve or lower resistance sleeve valve attached PS or ***0 series actuator (Germany). There is a servo magnifier in the pneumatic actuator and input control single (4 - *0mA DC or 1 - 5V DC) and single-phase power to control the pressure, flow, temperature, and liquid level. This valve is widely applied in power, gas, industry chemical, metallurgy, environment protection, light industry, teaching and scientific research areas.
