Year after year, the Mueller® Mark II Oriseal® Valve continues to demonstrate its free-turning and reliable-sealing characteristics in-field use. Consistent performance assured through 100% testing at 175 psig in both open and closed positions. Manufactured and tested to ANSI/AWWA C800 standard.
- Hefty tee-head and stem are integrally cast with plug to resist twisting and bending.
- Large top protects valve from curb box interference.
- Dirt seal keeps water, dust, dirt and other debris from entering top of valve.
- Low-friction plastic thrust washer at top of plug allow for consistent, low turning torque.
- Resilient O-rings seal both the top when valve is open and port when valve is closed. Each is fully supported in a machined groove.
- Straight plug is free-turning and eliminates tight metal-to-metal contact.
- The closed bottom has no nut to loosen; will not allow groundwater infiltration. No threads or critical bearing surfaces to be fouled with dirt.
