    摘要: Valve housing with high pressure inlet from line and high pressure outlet to load. Housing has coaxial bores with poppet or spool valve in small bore to control high pressure flow. Valve connected by stem to piston in large bore and valve is normally urged to closed position with fluid leakage through piston exiting through bleed hole. Closure for bleed hole operated by low pressure piston or diaphragm (1 psi or less) to build up pressure on free end of piston and move it to open valve.
