AM230 Top Guided Double Plug Relief PressureControl Valve

This top guided double plug relief pressure control valve, compared with AM220 series valves, It only needs smaller output actuator because of relief pressure by small plug when opening or closing the valve. reduce the unbalance force of medium, These valve is specially suited for polymer, slurry materials or high temperature,high pressure,high differential pressure fluids.The double plug structure extended the valve service life effectively..

*Globe valve with pneumatic actuator.
*Valve body optionally made of cast steel, forged steel, stainless steel and high-alloy steels or special materials.
*Valve plug with metal sealing.

Options
– Extension section or bellows seal
– Buttweld or socketweld connections
– Heating jacket
– Electric actuator
– Additional handwheel
– Reduced trim
– High temperature trim

Fail-safe positions
Depending on how the compression springs are arranged in the actuator, the control valve has two different fail-safe positions which become effective upon supply air failure:
Actuator stem extends (FC)
The actuator springs close the valve when the supply air failure. Also as air to open.
Actuator stem retracts (FO)

The actuator springs open the valve when the supply air failure. Also as air to close.
Accessories . Positioners, limit switches, solenoid valves, etc.
