Shut-Off Valves

  • Air Operated Valves

    PVC / polypropylene valves ideal for handling pure liquids, chemicals, acids and caustics in systems requiring a positive bubble-tight shut-off. Feature an automatic spring closing design for providing high flow rates with minimal pressure drop & unexposed hardware to allow sump mounting

  • Ball Valves

    Lateral-reducing ball valves featuring a true-union design for allowing multi-directional flow while retaining the ball under pressure and a reinforced shaft to eliminate stem breaks. Available in Geon, PVC, Corzan, CPVC, natural PP & Kynar PVDF materials

Check Valves and Backflow Preventers

  • Check and Foot Valves

    Self-closing thermoplastic valves featuring no internal loose or sliding parts to eliminate chattering and leak-free seals for preventing the reverse-flow of acids, caustics & chlorine solutions. Require a min cracking pressure of 0.5 psi to open the diaphragm

Pressure and Temperature Control Valves

  • Air and Vacuum Release Valves

    Normally open valves used with vacuum breakers to eliminate pockets of air during system start-up. Feature a self-guiding poppet-seal design that doesn't deform under pressure and a true union nut which allows fast valve inspection / removal with minimal pipe breakdown
