Hex Valve Product Line

 Primary/Orifice Block Valves > HG65 Orifice Block Valves



HG65 Series Orifice Block Valves are designed for compact side-by-side mounting on standard orifice flanges, condensate chambers, mercury traps, and seal traps. Two outlet ports are provided for impulse line connections or for pressure gauge or level gauge mounting. The HG65 is ideal for light hydrocarbons or utility service.


Features & Benefits




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.
