Shut-Off ValvesView all

  • 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

  • Electric Actuated Ball Valves

    Used for controlling the flow of liquid / gas with automatic voltage sensors for checking inlet pressures. Feature rugged polypropylene construction, anti-condensation heater, thermally protected motor & manual overriding for maximum equipment safety. Available in sizes ranging from 3/8 to 4 inches

  • Pneumatic Actuated Ball Valves

    Designed for automatic ON / OFF switching control of liquid or gas flow in pipelines. Feature sturdy plastic construction with a manual overriding mechanism for shifting the valve back to the energised position and preventing system failure. Available in corrosion-resistant Air X Air actuator model

  • Pneumatic Toggle Valves

    Drain the accumulated liquid from wet benches quickly & efficiently. Feature a pneumatic piston which keeps the unit bubble-tight sealed with up to 25 inches of water level & allows large full strokes for ultra-fast water evacuation. Available in 4-, 5- and 6-inch size variants

  • Sanitary Ball Valves

    Regulate the flow and prevent the entrapment of bacteria in piping systems used in dairy, medical, pharmaceutical & chemical processing applications. Feature an EPDM seal for a leak-free operation and excellent resistance against environmental hazards. Available in sizes ranging from 1/2 to 2 inches

Solenoid Valves and CoilsView all

  • Pilot Solenoid Valves

    Electrically controlled devices used for opening, closing and regulating liquid and gas flow in hydronic & irrigation systems. Feature PTFE bellows for reducing the vibration, thermal expansion, pressure thrust & piping load. Compatible with pipe sizes up to 2 inches

  • Plastic Solenoid Valves

    Suitable for multi-purpose applications like shut-off, distribution and mixing of fluids in water supply, wastewater treatment & dosing industries. Feature PTFE bellows for excellent flexion capability; ideal for use with all chemicals. Available in sizes ranging from 1/4 to 1 inch

  • Solenoid Valve Coils

    Designed for opening / closing the solenoid valves in both indoor and outdoor applications. Feature a corrosion-resistant polyester casing for protection against harsh environment & 1/2 in NPT conduit for easy connection without disassembling the entire unit

Check Valves and Backflow PreventersView all

  • 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

  • Flow Control Check Valves

    Equipped with an EPDM diaphragm capable of deforming under inlet pressure changes to regulate the flow rate and pressure of fluids through pipeline systems. Can operate in temperatures ranging from 40 degrees to 140 degrees F at a maximum pressure of 120 psi

  • Vacuum Breakers

    Prevent the backward siphonage of corrosive fluids & protect structural damage caused during draining. Feature a self-sealing diaphragm to regulate the vacuum pressure fluctuations and hold the vacuum at the pre-set point. Available in pipe sizes ranging from 1/2 to 1 inch

Pressure and Temperature Control ValvesView all

  • 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

  • Pressure Regulators

    Suitable for reducing the high inlet pressure of a gas / liquid to a controlled (pre-set) lower output pressure. Feature a PVC body for an anti-leak performance, rolling diaphagrams for pressure sensing & a Fail-Dry safety vent for alerting seal malfunctions. Available in 2 to 8 inch length dimensions

  • Relief Valves

    Designed for relieving excess pressure from a closed piping system by diverting a part of the flow back to the reservoir through an auxiliary passage. Feature a PTFE diaphragm and a thermoplastic body for contaminant-free sealing. Available in 1/2, 3/4 and 1 inch sizes

Liquid Level Gauges and Sight IndicatorsView all

  • Window Sight Flow Indicators

    Used for measuring the liquid flow rates, through a closed system, at a maximum line pressure of 200 psi. Feature sensors with switches to initiate the alarm, activate other equipment or shut the system. Integrated with a PVC constructed screen for quantitative readout

Pipe Fittings and CouplingsView all

  • Gauge Guards

    Protect and isolate pressure or vacuum instruments used with highly corrosive liquids and ultra-pure fluids. Feature a diaphragm for protection against system clogging & stainless-steel inserts preventing overtightening conditions. Available in PVC, CPVC, polypropylene & PVDF body variants
