Single Seat Control Valve 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 3810 series actuator. There is a servo magnifier in the pneumatic actuator and input control single (4-20mA DC or 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.
