HG12 Orifice Block Valves
The HG12 features a built-in vent or bleed screw on the outlet side of the valve. In process line mounted instrument or signal line tubing, venting, or line filling capabilities can be an added feature
- 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.
