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.

Sherwood Valve D28-274

A robotically welded body joint. Full-size ports for unrestricted flow. These ball valves employ the latest robotic welding technology. Every continuous welded body joint is 100% factory tested to ensure positively leak-free performance. Dual Teflon ball seals surround a polished brass or carbon steel ball at each end. A secondary seal becomes effective if foreign material scores the primary seal - even in extremely unfavorable conditions such as compressor burnout - a Superior exclusive!. WA/WAS Series Ball Valves are constructed using a forged brass body with copper tube extensions on all sizes. Mechanical internal forged stops ensure positive open or closed positions - another Superior exclusive. Full open to full close with 1/4 turn. All sizes incorporate a dual stem seal design utilizing Teflon packing compressed by an internal packing nut forming the primary seal. The unique seal cap design permits valve operation without removal of the seal cap and uses Teflon gaskets to provide a secondary seal - a third Superior exclusive! There are no synthetic O-rings. Ball internal relief port design ensures shut-off in either direction of flow - even during evacuation of the system. Full flow ports in all sizes 3/8" through 3-1/8 Inch. These ball valves are non-directional flow valves and may be installed in any position.
