UHP PFA Air-operated Diaphragm (3/4 inch) 3 Way Valve – PV-16 Series

The PV-16 Series PFA Diaphragm Valve offers high leak integrity and excellent resistance to corrosion. It is available in 3-way configurations and is designed for ultra-high purity (UHP) and aggressive liquid and gas applications.

The PV-16 Series is a 3/4 inch PFA air-operated diaphragm valve that is designed for use in ultra-high purity (UHP) and aggressive fluid handling applications, including semiconductor manufacturing operations. The valve is available in 3-way configurations and utilizes a molded PFA body with precision-machined sealing areas for superior leak integrity and chemical resistance.

The PV-16 Series is equipped with a one-piece modified PTFE diaphragm, which provides excellent flexibility and higher cycle life than conventional PTFE. The valve also features an Fluoropolymer-coated stainless steel spring, which reduces the effects of corrosive environments and enables compatibility with a wide range of process media. Depending on customer requirements, PV-16 Series valves can be fitted with a variety of port configurations, including Parflare and Parbond tube fittings. The fittings reduce assembly and installation time, while ensuring a leak-tight seal for performance in applications where cleanliness is critical.

The PV-16 Series PFA valve's exacting design controls seat and diaphragm stresses to provide a reliable and maintenance-free service life. Its tongue and groove seal ensures a positive diaphragm to body seal, resulting in high cycle life, lower replacement costs, and isolation of process media from the actuator. The valve features a full 3/4 inch orifice with no restrictions for maximum flow in a compact package at working pressures up to 120 psig. Flow capacities are dictated by configuration and end type (up to 7.9 C?v for PV-16 with Parbond or Parflare connection). The valve's actuation pressure ranges from 60 – 120 psig.
