Orifice Block Valves  - PG65 Series

PG65 Orifice Block Valves


The PG65 block valve is designed for compact side-by-side mounting on orifice flanges and orifice settings, as well as for use with condensate chambers, mercury traps, and seal traps. The slim design enables side-by-side mounting on 2-1/8" centers without staggering the valves with unequal length nipples as required with other valves. This valve provides two outlet ports for use as impulse line connections, pressure gauge mounting or level gauge mounting.


  • Compact, Side-by-side mounting - The slim design of Hex primary block valves allows side-by-side mounting on standard orifice flanges, and reduces the required installation space. The shorter profile and lower weight make these valves ideal for tight installation.

  • Reduce Potential Leakage, Costs - Using Hex primary valves cuts the number of components required on traditional orifice flange installation, resulting in fewer threaded connections and lower installation costs.

  • Non-Rotating Tip (NRT) Stem - Provides tight, repeatable shutoff without galling or cross-scoring that occurs on ball type stems. The NRT conical stem tip stops rotating when it contacts the seat, so further torque turns the stem, but not the tip.

  • VOC Emission Compliance - Unique TFE-Chevron and high temperature 1625G/Grafoil/1625G packing designs have been certified to meet and beat the 100 ppm EPA 1998 Emission standards.
