Overview
The Hex Valve HM591U3331412 is a compact two-valve instrument manifold engineered for static pressure instrumentation systems. This stainless steel manifold combines shutoff and bleed valve functionality into a single, cost-effective assembly. The HM591U3331412 eliminates the need for multiple individual nipples, pipes, elbows, and gate valves, streamlining installation and reducing potential leak points in your pressure measurement lines.
Key Features
- Two-valve design provides both isolation and bleed capability
- Stainless steel body with integral hard seat for durability
- 316/316SS NRT stem and tip materials ensure corrosion resistance
- TFE/Chevron packing for reliable sealing across pressure cycles
- 1/2″ NPTF female inlet and outlet for direct gauge and transmitter connections
- Significantly fewer threaded connections compared to traditional piping assemblies
