Orifice Block Valves  - HO25 Series

HO25 Orifice Block Valves


The HO25 features an OS&Y bolted bonnet and two outlet ports. The HO25 is more compact and has a shorter profile than the HG65 model.


  • 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.
