The Series PRU is an ultra-pure pressure regulator designed for chemically inert operation in high-purity water and chemical applications, featuring an all-PTFE internal design with a convoluted PTFE diaphragm that isolates the spring from process media. It supports inlet pressures up to 120 psi and maintains downstream pressure between 5 and 100 psi. The regulator is available in PTFE, Kynar™ PVDF, or natural polypropylene bodies with flare, socket, or NPT connections, and is not designed to fully close under no-flow conditions. Dimensions for 3/4" and 1" sizes are given as A: 4.25 in (104.1 mm), B: 2.5 in (189.8 mm), C: 8.75 in (46.5 mm), and D: 4.50 in (100.2 mm).
Series PRHU Downstream pressure reducing valve features metal ion-free EPDM large area rolling diaphragm, ultra-smooth operation and isolated spring control. BCF spigots in 1/2″ – 3″ or 20 – 90mm sizes; Kynar 740 body and Class 100 clean/double bag procedure standard. Provides highest flow with minimal pressure droop among high purity regulators; set pressure range 10-125 PSI.
