Reguvale's industrial control valves provide precise flow, pressure, temperature and level control for process industries. The product line includes pneumatic diaphragm globe valves, electric actuator modulating valves and self-operated pressure regulators, all designed for stable throttling performance and long service life.

Body materials include carbon steel WCB, stainless steel SS304/SS316 and ductile iron, with flanged ends to ISO 7005-2 / EN 1092-2 / ASME B16.5. Trim configurations are available in single-seat, cage-guided and pressure-balanced designs to match your Cv requirement, characteristic curve and pressure drop. Actuators can be supplied with YT-1000 / YT-1050 positioners, 4-20mA smart positioners, solenoid valves and limit switches.

Each valve is factory calibrated for stroke and leakage, with shell and seat hydrostatic tests, and can be supplied with material test certificates and third-party inspection reports.

Key Features

✓

Precise Modulating Control

Equal-percentage or linear flow characteristics give accurate throttling for flow, pressure and temperature loops.

✓

Pneumatic & Electric Actuators

Choose diaphragm/spring pneumatic actuators or 24V/220V/380V electric actuators with 4-20mA modulating input.

✓

Self-operated Pressure Regulation

Pilot-operated and direct-acting pressure regulators maintain downstream pressure without external power.

✓

Smart Positioner Options

YT-1000, YT-1050 and digital smart positioners with HART/Profibus feedback for accurate valve positioning.

✓

Interchangeable Trim

Single-seat, cage-guided and pressure-balanced plugs are available to match Cv, noise and cavitation requirements.

✓

Factory Calibration & Test

Every valve is stroke-tested, calibrated and hydrostatically tested before shipment; MTC available.
