Abstract
Relatively simple partially or completely pressure balanced valves are disclosed having relatively low friction and gas forces to be overcome by a solenoid actuator. Various devices are provided for sealing of the valve members to maintain low leakage of gases through the valve or into the actuator. Movable members of the valve and actuator are engaged but physically separate so they may be separately replaced. Various actuators may by applied with various valve assemblies for flexibility in meeting the requirements of alternative applications.
