ABSTRACT:
A portable hydrostatic test apparatus for pressure testing fluid system components. Hydraulic fluid is pressurized and serves as the pressure source for imposing a desired test pressure on a water filled system. The apparatus includes a pneumatically operated control valve to control a directional control valve in the hydraulic system. The several valves in the hydraulic system are mounted on and interconnected through an internally ported manifold to eliminate hoses.
