Hold-Down Valve Testing Machine ISO 5208 Compliant with DN15-1200 & PN1.6-48MPa Range

Product Description

The WPT-2 Hold-Down Valve Testing Machine is a high-integration comprehensive testing system for valves, integrating electromechanical control, hydraulic drive, pressure testing, and fluid medium storage & circulation. By positioning the valve flange surface and using a movable back-jaw clamping method, it eliminates additional external forces that could affect test results, ensuring precise and reliable performance testing of valves. Equipped with hydraulic drive and PLC computer control, it enables automated and accurate testing processes.

Product Applications

Widely used in industries such as valve manufacturing, petroleum, petrochemicals, nuclear power, and chemical engineering, as well as valve maintenance departments. It is designed for performance tests (strength, tightness, leakage) of various high, medium, and low-pressure valves with nominal diameters from DN15 to 1000mm, including gate valves, ball valves, globe valves, and check valves. Test media can be water, gas, or oil, meeting diverse industrial testing needs.

Product Highlights

High Integration: Combines electromechanical control, hydraulic systems, pressure detection, and fluid medium circulation in one unit for complete and stable performance.
Advanced Automation: Utilizes hydraulic drive and PLC computer control to improve work efficiency and reduce labor intensity.
Wide Testing Range: Covers valve diameters from DN15 to 1200mm (NPS 1"–28") and pressure ranges from PN1.6 to 48MPa (Class 150–2500lb), suitable for various valve types.
Precise Clamping: Adopts valve flange surface positioning and movable back-jaw clamping to meet national and international pressure test standards, ensuring accurate test results.
Durable Construction: Made of 25# carbon steel for long-term stable operation in harsh industrial environments.
Versatile Operation: Supports hydraulic drive, PLC control, and button control to fit different user preferences and scenarios.
Easy Connection: Flange connection design enables stable installation and convenient disassembly.
Authoritative Certification: Awarded new product certificates and national patents, guaranteeing advanced technology and reliability.
