Piloting the Way to Precision Control! LCM Industries stocks the Farris™ Series 3800 modulating pilot operated control valve. These innovative integrally cast, flanged semi-nozzle valves are provided as self-contained units actuated by a snap-acting pilot valve. Main Valve body is Carbon Steel (also available in SS) with Stainless Steel trim. The Pilot Control Valve comes standard with SS primary components. All valves in this series are certified under Section VIII of the ASME Code for Air, Gas, Vapor & Liquid Service.

MAIN VALVE FEATURES
- Soft Goods • Viton® is standard for both main and pilot control valves. Buna N, Neoprene, ethylene propylene, silicone and Teflon® are optionally available.
- Bubble-tight Closer to Set Pressure • Series 3800 valves operate bubble tight at higher operating pressure to set pressure ratios, allowing operators to run very close to the system’s maximum working pressure.
- Unaffected by Back Pressure • Unlike a direct spring loaded valve, the pilot operated valve’s set pressure is not affected by back pressure.
- Convertible Design • The unique convertible design minimizes the number of components and maximizes their interchangeability, reducing parts inventories and costs.
- Convertible Nozzle • Threaded convertible nozzles can be removed and replaced easily without factory service with common tools while the valve is in line.
- Fewer Internal Components • The valve design requires no lift stops and the main valve opens fully at set pressure.
- One-Piece Body • Integrally cast flanges assure the highest material integrity and eliminates problems with welding.
