PolyPure® ball valves feature a true union design that simplifies installation and removal, making them highly user-friendly. They are equipped with PTFE seats and energized O-rings that minimize wear and extend the valve’s cycle life. Dual shaft seals effectively prevent leakage, while a heavy-duty, large diameter shaft eliminates flexing and breakage. The PTFE bearing on the shaft reduces friction and wear, and the stem design is “blow-out” proof for added safety. With a fully concentric and mirror-polished ball, these valves ensure smooth and leak-proof operation. Their multi-directional flow design prevents incorrect installation, and a smooth flow path helps reduce pressure loss.

Introducing, the next-generation model T-241 forward pressure regulator for ultrapure water systems. The T-241 pressure regulator is a forward pressure regulator that controls upstream pressure fluctuations to critical points of use.
The T-241’s internal parts have been significantly improved for optimum purity and minimal particle shedding. The wetted elastomers have been upgraded to premium materials, and internal surfaces have been enhanced. The parts are cleaned and assembled by Asahi/America’s manufacturing partner, AGRU, in their state-of-the-art Austrian facility. All wetted parts are cleaned in an automated six-phase cleaning system, then assembled and packaged in a Class 100 cleanroom.
The T-241’s body features an integrated gauge guard, which eliminates the need for additional instrument fittings. The included pressure gauge has been upgraded to a robust stainless steel housing. The regulator setting is easily adjusted by an integrated set screw; protected by a top cap. The T-241 is available in high purity PVDF.
Designed to meet stringent particle-shedding constraints for next-generation microelectronics manufacturing, the T-241’s enhanced features make it the best solution for your next tool hookup project and for replacing installed regulators that are causing yield issues.
