F300 Pressure Regulator

F300 Pressure Regulator

Product catalog summary

Overview: The F300 series is a pilot-operated pressure regulator designed for applications requiring pressure reduction. It minimizes sudden downstream load changes and includes an internal relief valve for overpressure protection, making it ideal for fixed factor billing.

Specifications: The regulator is manual, direct-acting, self-operating, spring-loaded, and adjustable. It is suitable for compressors, gas engines, and service regulators. The maximum emergency outlet pressure is 25 PSIG, with various pressure ranges and port sizes available. The temperature range is from -20˚F to 180˚F (-29˚C to 82˚C), and the approximate weight is 10 lbs (4.5 kg).

Materials of Construction: The body is made of ductile iron or WCB steel, with aluminum used for the adjusting screw, bonnet, closing cap, lower casing, and orifice. The diaphragm and molded seat assembly are made of nitrile.

Pressure and Flow Capacities: The document provides detailed tables for maximum inlet pressures and flow capacities in SCFH for different orifice sizes and set pressures, both for internal and external registration configurations.

Part Matrix and Rebuild Kits: The F300 part matrix includes options for internal or external registration, port sizes, spring ranges, special construction, orifice sizes, port orientation, and body material. Rebuild kits are available, including diaphragms, disk holders, cap gaskets, and O-rings.

Dimensions and Parts Drawing: Detailed dimensions and parts drawings are provided, along with a list of parts and their corresponding part numbers.
