BRONZE CHECK VALVES
SCF SERIES
The SCF Series is a Class 150 bronze swing check valve designed for reliable one-way flow control in industrial and commercial piping systems. Its full-port swing disc provides minimal flow restriction and low pressure drop during operation, while the integral body seat provides positive sealing when flow reverses. Constructed from C95800 nickel aluminum bronze, the valve offers excellent corrosion resistance for demanding industrial and marine environments. A bolted cover provides convenient access for maintenance, and the valve can be installed in either horizontal or vertical up-flow piping. Designed and tested to recognized API and ASME standards, the Series SCF is well suited for water, oil, gas, and many chemical services across a wide range of operating temperatures.

SPRING CHECK VALVES
VSC SERIES
Engineered to prevent backflow and protect pumps, equipment, and process lines across chemical processing, oil and gas, steam systems, water treatment, pharmaceutical, food and beverage, and general industrial service, the VSC Series is a compact in-line spring check valve available in 1/2″–3″ sizes with investment-cast CF8M stainless bodies, 316 stainless internals, and PTFE or TFM1600 seats for compatibility with chemicals, steam, and a wide range of media. Its low-cracking-pressure design with optional Inconel spring opens quickly under forward flow and closes positively against reverse flow, while threaded FNPT ends and a short face-to-face make installation simple in tight piping runs. Rated to 800 psi (1/2″–2″) and 600 psi (2½”–3″), built to ANSI B1.20.1 and ISO 9001 standards, and 100% air-tested under water at 80 psi, the VSC Series is the reliable, install-and-forget backflow protection your system needs.
