DELCO Y43H Pilot Operated Piston Pressure Reducing Valve, Steam / Air, Flanged

✅Pilot Piston Technology: Unlike direct-acting valves, this model uses a sensitive pilot valve to control a larger main piston, offering superior responsiveness and the ability to handle high flow rates with minimal pressure droop.

✅Stable Outlet Pressure: Engineered to maintain a constant downstream pressure within ±5% of the set point, even when the upstream pressure varies significantly, ensuring consistent performance of downstream equipment.

✅Wide Adjustment Range: Features an easily accessible adjustment screw (protected by a cap) that allows operators to precisely fine-tune the outlet pressure across a broad spring range (e.g., 0.1–1.6 MPa) to meet specific process needs.

✅Robust Steel Construction: Available in Cast Steel (WCB) or Stainless Steel (304/316) bodies, capable of withstanding high temperatures (up to 425°C for steam) and harsh industrial environments.

✅Built-in Strainer Protection: The pilot system includes a fine filter screen to prevent debris from clogging the sensitive control passages, extending the service life of the valve and reducing maintenance requirements.
