Hydropro™ Universal Flange Valve Tester


The HYDROPRO™ Universal Flange Valve Tester – Clamp Fixture Clamps and seals flanged valves for pressure testing. Capable of hydrostatic tests up to 9,700 psi and low-pressure air tests up to 125 psi.* Our unique tilting feature rotates clamped valves 90° from horizontal to vertical, ensuring removal of all air prior to pressurizing the system. Paired with an HYDROPRO™ Hydraulic Flange Seal this is the best way to test API valves, where cross body pressure on the valve is not an option.


Type of Valve:
Ball, globe, gate, & check valves

Valve Clamping:
Flange clamping

Types of Tests:
Hydrostatic & low pressure air seat leakage

Maximum clearance for actuated valves.

Tilt option allows for water fill in the orientation best suited for removing air.

Pairs with the HYDROPRO™ Console and SMARTEST™ Data Acquisition System for a complete valve testing solution.

Pairs with the HYDROPRO™ Hydraulic Flange Seals for sealing both ends of the valve and for bidirectional testing.
