The SAFETY RELIEF VALVE TESTER performs SRV set pressure and seat leakage tests. Our unique ‘J’ tube design allows for a free flow of gas or water from the source to the SRV being tested providing a cushion of air under the SRV seat to prevent seat damage. The control panel is ergonomically designed 90° from the clamp fixture to provide a splash shield barrier between the operator and the clamp table.

ROBUST
- Every component in the SAFETY RELIEF VALVE pressure circuit is OEM-certified to the maximum specified testing pressure of the system for increased quality, durability, and safety.
- Heavy-duty console walls are built with 12-gauge steel to protect internal components from damage, making this tester rugged and durable for long life and reliable operation in industrial environments.
- Safety Interlock system with test pressure sensing components that will not release the clamp pressure until the test pressure drain valve is opened and internal test pressure is released.
- ISO 9001:2015 certified manufacturing ensures all CALDER products are manufactured to the highest quality standards.
- Standard 2-year warranty is the longest in the industry! We’re confident in our quality, and we back it up! And – ask us how to extend your warranty out to 5 years . . .
EASY TO USE
- The hydraulic clamping control panel is conveniently located at the clamp fixture for quick and secure valve positioning and clamping.
- Test control panel location provides a splash shield between the operator and the clamp table.
- Viewing window allows observation of the valve during the testing process.
- Intuitive control panel layout makes performing a test procedure efficient and easy for the operator.
- Extensive operating manual contains easy to follow tips and includes step-by-step set up instructions for various valve testing operations.
