True Union Proportional Flow Control Ball Valves
The percentage of flow through the valves with either flow curve is equal to the degree of opening. As the valves are opened or closed, the flow varies in direct proportion to the valve opening. This permits predictable, accurate control of the downstream flow rate with a 1/4-turn valve.

True Union Ball Valves: CPVC with Viton Stem Seal
"The True Union Ball Valve is rated to 225 PSI at 70°F. The "True Union" enables you to remove the valve from the system for maintenance without disturbing piping connections. EPDM seals and seats are standard (PTFE is an option) and designed to be compatible with aggressive fluids. The full port design ensures maximum flow at a low pressure drop".

COMPACT OEM PVC BALL VALVES
Light weight and compact PVC ball valves idea for OEM applications due to its' high quality and low cost. The internal components are completel encapsulated within the valve body in a one step manufacturing process. There is no danger of leakage through assembled parts.
These valves do not require adjustment because all the internals are sealed wtihin the one-piece valve body.

True Union Ball Valves: Polypropylene with Viton Stem Seal
"The all Polypropylene construction of these true union ball valves eliminates rust or corrosion issues. This ensures that the valve will never stick, jam or fail to operate like a metallic valve might due to corrosion. The True Union Ball Valve is rated to 225 PSI at 70°F. The ""True Union"" enables you to remove the valve from the system for maintenance without disturbing piping connections. EPDM seals and seats are standard (PTFE is an option) and designed to be compatible with aggressive fluids. The full port design ensures maximum flow at a low pressure drop".

Series EA True Union Ball Valves with Low Cost Electric Actuator
The EA Series automated true union ball valve offers a low cost method of automating ball valves. Compared to competing brands that use "throw-away" (non-repairable) actuators, the EA Series is fully serviceable.
The all PVC construction of these true union ball valves eliminates rust or corrosion issues. This ensures that the valve will never stick, jam or fail to operate like a metallic valve might due to corrosion.

Proportional Control Ball Valves
These valves can provide a slow opening and fast opening flow curve with the percentage of flow equal to the degree of the valve opening. These provide predictable and accurate flow control with only a 1/4 turn of the valve handle. Compatible with pneumatic and electric actuators with positioners for automated modulating service applications. PVC or CPVC construction with FPM or EPDM seals for Methane Gas Recovery, Fill Station Lines, Lateral Take Off Line Flow Control, Flow Reduction for Pump Systems and Flow Control from Tanks.

True Union Ball Check Valves
Prevent reversal of flow in piping systems to protect pumps, filters and other process equipment with true union ball check valves manufactured from PVC, Corxan, CPVC and PPL. Line pressure moves the solid plastic ball off the elastomer seat, opening the valve. The back pressure seals the ball against the seat when the inlet flow stops. True union design enables easy installation and removal from piping system. FPM and EPDM seals, works in any direction expect downflow, optional foot valve screens can be added for pump priming.

Y Check Valves
Prevent reversal of flow in piping systems to protect pumps, filters and other process equipment with true union ball check valves manufactured from PVC and CPVC with FPM seals. Y check valves enable servicing without removing the valve from the pipeline and they work in any orientation as long as there is a minimum 2 PSI back pressure.

Spring Loaded Y Check Valves
These Y check valves are spring loaded to creat a seal even in the absence of back pressure. These are often used to reduce water hammer when pumps are started in an empty, open line. These are hand adjustible for opening at pressures from 2 to 15 PSI. PVC construction with FPM or EPDM seals, these Y check valves work in any orientation. True union connections are available.

Swing Check Valve
Designed for high pressure and temperature applications where elimination of metal components is desired. PVC, PPL and CPVC construction with FPM or EPDM seals, flanged connections. These swing check vavles can be installed horizontally or vertically and no flange gaskets are required. Options include counter weight for closing assistance (vertical installations), limit switch for position indication and spring assist closure.
