  • Introduction
  • Specifications
Pneumatic diaphragm through single-seat adjusting valve, is the general actuator of automatic control system. Simple structure, reliable action, convenient maintenance, widely used in chemical, petroleum, power, metallurgy for automatic adjustment and  remote control
Structure principle
Pneumatic diaphragm through single-seat adjusting valve, made up of pneumatic diaphragm actuator and through single-seat valve
Small flow valve is single-seat structure, impact structure, small size, light weight, convenient maintenance
Conical valve spool, small control flow, good sealing, precise regulation
Principle: input signal pressure that action on air room of diaphragm, drive valve spool, travel of valve spool changes, change the flow area, then regulate the processing parameters of pressure, temperature, flow and liquid level
