Water Hydraulics

Specializing in standard and custom high-pressure valves for water hydraulics and other high-pressure water systems.

Industrial piping system with several connected valves and pressure regulators, including white and gray components, metal pipes, and a blue-handled valve, set against a background of machinery and equipment.

Rubber Compression or Transfer Molding Press

Model #D-1055-23,
3” 3,500 PSI Two-Pressure Valve assembly with automatic high-pressure inlet valve, pressure reducing valve for tonnage control, high-pressure safety shutoff, and 3” two-way stop valve to hold the ram mid-stroke for loading material or unloading parts.

A metal control valve with pipes connected in multiple directions, located indoors near black railings and a beige wall. A paper tag hangs from the valve.

Pump Unloader or Bypass Valve

Model #D-1012-NO,
1-1/4” 3,500 PSI Two-Way Valve used to bypass discharge flow of a positive displacement pump back to reservoir. A normally open valve is usually chosen so the pump will unload in case of a control failure.

A large industrial Gardner-Denver machine sits on a wooden pallet. The machine is blue-gray, with pipes, gauges, and a labeled cover on the left side. The background is dark and not clearly visible.

Pump Unloader or Bypass Valve

Model #D-1010-NO,
3/4” 3,500 PSI Two-Way Valve mounted on a Triplex plunger pump to bypass water from the discharge side back to the suction side at nominal pressure.

Two tall, cylindrical industrial tanks stand side by side inside a large factory or warehouse, connected by pipes and surrounded by metal structures and walkways.

Air-Over-Water Accumulator Safety Shut Off Valve (ASSO Valve)

Model #D-1268,
6” 3,000 PSI Pilot Operated Check Valve (PO Check) is used to protect against loss of pre-charge in the accumulator when liquid level drops too low. The valve is mounted at the discharge port and controls flow to the system through the blue pipe.

Industrial piping system with a large valve, motorized actuator, and black pipe mounted on a metal platform. A vertical orange ladder is attached to the platform, with pipes running overhead in the background.

Air-Over-Water Accumulator Safety Shut Off Valve (ASSO Valve)

Model #D-1268,
6” 3,000 PSI Pilot Operated Check Valve (PO Check) used to prevent pre-charge air from escaping accumulator when liquid level drops too low.

Two metal hydraulic flow control valves are mounted on a steel frame with pipes and hoses connected to them. Labels and numbers are visible on the valves. Background includes additional industrial piping.

High-Pressure Check Valves

All stainless steel
1” 10,000 PSI
Check Valve prevents water flow in the reverse direction.
