It combines a powerful 65-ton vertical clamping press with a dual-motor hydraulic power pack to deliver test pressures up to 135 bar (1958 PSI). As a butterfly valve test bench and check valve testing machine, the rig is optimized for hydrostatic pressure testing, leak detection, body integrity validation, and seat verification across 2″ to 12″ (DN50–DN300) valve sizes.

Featuring a digital control panel, an integrated leak detection camera, and full safety interlocks, this hydrostatic valve tester ensures precise, reliable hydrostatic and leak testing for industrial valves. Engineered for rugged operation, it is ideal for valve manufacturers, utilities, and maintenance facilities that need a dependable industrial valve leak tester for high-volume valve performance validation.

Built rugged. Built smart. Built for industrial reliability.

The rig uses a high-tonnage hydraulic press with programmable clamping and pressure regulation, supported by an advanced power pack unit, safety interlocks, and a visual camera inspection system — validating valve shell strength, detecting seat and body leaks with a liquid test medium, and enabling rapid cycle testing for mass-production or maintenance environments.

Architecture

Six subsystems, one test bench.

Every subsystem of the valve testing skid is designed, integrated, and operated from a single digital control panel, giving operators a complete industrial valve testing system in one footprint.

Working principle & step-by-step testing operation

The Valve Test Rig performs hydrostatic testing by clamping the valve between two hydraulic working plates, pressurizing it with liquid (typically water or a compatible hydraulic test fluid), and inspecting it for leaks or body deformation.

Startup: switch on the main power supply and the auxiliary system; ensure hydraulic oil level is adequate and check filter health.
Clamping: place the valve between the upper and lower working plates; start the clamping motor (7.5 HP); use the clamping cylinder to vertically lock the valve via hydraulic pressure (up to 25 bar).
Pressure application: start the loading motor (2 HP); set the desired test pressure using controller parameters (C1 for desired, AL1 for alarm threshold); adjust relief valves accordingly for high- or low-pressure tests.
Leak detection: the leak camera positioned below visually monitors the valve body and seat for any seepage.
Unclamping and test completion: after test duration, pressure is released; select UNCLAMP to retract the cylinder; switch off the loading and clamping motors.

Capabilities

Clamping range: single flange, dual flange, or proportional clamping.
Pressure testing types: Shell (Body) Hydrostatic Test · Seat Leakage Test.
Valve material compatibility: suitable for metal-seated and rubber-seated valves.
Test medium: water or test-compatible non-compressible liquids.

Construction and material

Main frame: rigid welded structure with heavy steel sections.
Clamping pillars: hardened steel, designed for no-flex operation.
Hydraulic cylinders: high-precision, chrome-plated shafts with leak-proof seals.
Filtration system: Hydac and Rexroth make, ensuring maximum fluid cleanliness.
Cooling system: radiator-based oil cooler to prevent fluid overheating in long operations.

Safety features

Emergency stop switches strategically placed.
