Polyethylene (PE) valves are increasingly used in modern piping systems, particularly in gas distribution, water supply, and geothermal applications. PE valve testing equipment is therefore indispensable for verifying mechanical integrity, sealing performance, and durability under varying service conditions.
Shijiazhuang Zhongshi Testing Machine Co., Ltd. has developed a dedicated line of PE valve testing systems to meet these critical testing needs. These machines are built with durable components capable of handling the flexible yet robust nature of polyethylene materials.
Main Testing Procedures:
Hydrostatic Pressure Resistance: Simulates the internal pressure PE valves are expected to withstand over extended periods.
Leakage Testing: Both air and water testing methods are used to assess valve seat and shell leakage.
Thermal Cycling: Alternates between hot and cold water to simulate daily operational conditions and detect thermal fatigue.
Endurance Cycling: Repeats open/close cycles thousands of times to test mechanical durability.
System Specifications:
Valve Size Range: DN20–DN160 or larger upon request.
Control System: Programmable logic controller (PLC) with touchscreen operation.
Accuracy: ±0.5% of full scale for pressure readings.
Optional Add-ons: Flow rate measurement, high-temperature modules, and remote data access.
Use Cases and Compliance:
The systems are especially beneficial for valve manufacturers and utility suppliers who require compliance with standards such as ISO 4437 and EN 1555. PE valves used in underground installations or in corrosive environments must pass rigorous testing, which our equipment supports through configurable test parameters and modular setups.
