Product Overview
The SENTRY EQUIPMENT CORP VREL Variable Pressure Reducing Valve is a precision-engineered process control valve designed to maintain a stable, reduced downstream pressure from a higher upstream source. Manufactured by Sentry Equipment Corp, a recognized name in industrial sampling and process control instrumentation, the VREL series operates on a direct-acting, spring-loaded diaphragm or piston sensing principle. The valve continuously modulates its internal trim in response to downstream pressure feedback, ensuring accurate pressure regulation across varying flow demands. As a variable pressure reducing valve, it allows operators to adjust the setpoint within a defined range, making it suitable for a broad spectrum of industrial fluid and pneumatic control loops where precise, repeatable pressure reduction is critical to process integrity and equipment protection.
