The core of the device is the transmission of mechanical force in the vertical direction. During operation, the high-strength screw located above the equipment rotates under the drive of the driving device motor, pushing the upper sealing pressure plate to move vertically downward. The tested valve is placed horizontally on the lower sealing seat, and the downward pressure generated by the screw acts on the upper flange of the valve through the upper pressure plate, tightly pressing it down on the lower sealing seat. The sealing elements on the upper and lower pressure plates deform under pressure, forming axial seals on the flanges at both ends of the valve, thus creating conditions for subsequent pressure testing.

Product features and advantages

Simple structure, sturdy and durable: pure mechanical transmission, extremely low failure rate, almost maintenance free, long service life.
Small footprint and convenient operation: the vertical design saves valuable ground space; The valve is placed horizontally, and the clamping height conforms to ergonomics, making loading and unloading easy.

Extremely low investment and maintenance costs: no need for hydraulic systems, no oil leakage troubles, initial purchase cost and long-term maintenance cost are much lower than hydraulic equipment.
