Part of Superior's trusted horizontal or vertical check valve line, these valves are designed for an easy install and use in your refrigeration or air-conditioning system. For years, this Y type of valve has been the most popular design in the refrigeration industry. The internal parts can easily be removed and reassembled after soldering. This basic Y type design reduces pressure drop to a very low level. The Teflon seat insert rapidly conforms to the cone style of seating surface in the body. This ensures positive shut-off characteristics. This valve minimizes leakage even at the lowest back pressure. A specially designed secondary seat backs up the primary seat. After approximately 10000 cycles of operation, the secondary seat becomes effective. This is done to ensure even better shut-off characteristics as the valve wears into service.
