Details
Hansen low pressure drop refrigerant shut-off valves are designed to be butt-welded directly to steel piping, thereby eliminating potential leaky flanges or threaded joints and simplifying installation. Cast steel bodies are lightweight, yet have substantial wall thickness to overcome corrosion potential. The cast steel body is rigid, reducing the potential for seat leakage due to flexing of the valve body under abnormal conditions. The "heart" of Hansen shut-off valves is the patented no-leak seal-plus-stempacking design. This seal design is used exclusively on Hansen shut-off valves and virtually eliminates stem seal leakage.
Applications
Typical uses include:
- Ammonia refrigeration system suction, liquid, discharge, recirculating liquid, hot gas, thermosyphon, and oil lines, using handwheel or seal cap models.
- The low friction, no leak stem seal design permits the use of chain actuation for crossover applications without the need to retighten the packing.
- Steel pipe portions of halocarbon, commercial, industrial, and air conditioning systems, using seal cap models.
