VP*46E-X660/X661

The VP-X660/X661 series residual pressure relief valves completely shut off the air supply, putting the machine in isolation mode for long-term idle states. It includes a soft-start option to ensure controlled system initialization when paired with mechanical regulators. Available in both normally closed and normally open configurations, it eliminates 100% of air loss caused by micro-leaks in downstream equipment over long periods of inactivity. It’s favored by safety engineers and plant operations managers because it mitigates the safety hazards associated with uncontrolled dumping of residual pressure and the abrupt pneumatic surges upon machine start-up.
