Valve Testing Equipment Application Testing
01
Functional Testing
Verifying the valve opens, closes, and regulates flow according to specifications. This can involve measuring opening/closing speed, stroke length, and flow characteristics at different valve positions.
02
Leakage Testing
Identifying and quantifying any leakage that occurs when the valve is closed. This helps ensure system integrity and prevent potential safety hazards or product contamination.
03
Pressure Resistance Testing
Assessing the valve's ability to withstand specified pressure loads without structural failure. This is crucial for valves used in high-pressure systems.
● Gas and water testing
● Usually hydraulic clamping
● High test pressures
Closed water circuits (fresh water supply)
Usually up to 385 bar (5580 psi) water and 300 bar (4350 psi) air
Safety tension with hydraulic clamping unit
External testing option
Simple operation
Long service life
Valve Testing Equipment Safety Protection
Operators should wear corresponding protective devices, such as helmets, safety shoes, gloves, etc.
Set up obvious safety warning signs in the test area to prevent unrelated personnel from entering.
Don't stand on the front of the testing valves when the pressure is holding.
Protection shields are essential to protect workers from injury.
Do not wear loose clothing or jewelry while using revolving power tools. Tie back long hair or wear appropriate hair protection to prevent hair, clothing, or jewelry from being caught and pulled by clamping claws or cylinders in motion.
