Abstract (en)
[origin: WO2012034953A1] A valve (200) including a housing (201) and a process fluid supply port (112) formed in the housing (201) to receive a process fluid is provided. The valve (200) includes a piston (202) movable within the housing (201) between an open position and a closed position. The piston (202) includes a first pressure-compensating surface (315) in fluid communication with the process fluid supply port (112) when the piston (202) is in the open position. The piston (202) further includes a second pressure-compensating surface (316) with a first portion (210) in fluid communication with the process fluid supply port (112) when the piston (202) is in the open and the closed position and a second portion (208, 317) in fluid communication with the process fluid supply port (112) when the piston (202) is in the open position.
