<Features>
- Supports a wide range of applications
Stainless steel discs and EPDM rubber sheets are available for various types of line-fluids without concern for corrosion.
- Stable operating torque
A pair of stem bearings assembled around the upper and lower stems prevents stem galling, stabilizes valve operating torque, and ensures smooth and trouble-free disk rotation.
- Actuator mounting flange ISO5211 on site
The actuator mounting pads on the neck are designed to allow direct field mounting of actuators with ISO5211 mounting flanges.
- Condensation prevention (long neck type)
No insulation is required to block the heat of the fluid from being transferred to the valve operating device along the neck of the stainless steel. Condensation is minimized even for cold water services.
-
- Anti-rust measures
All the main components, such as stems, discs, necks, neck connectors, and bolts, are made of stainless steel and are highly corrosion resistant.
- S-Shaped Spherical Disk for High Sealing Performance <Patented>
Kitz’s proprietary S-shaped valve disc with a spherical surface is uniformly in close contact with the rubber liner, providing excellent sealing performance while reducing operating torque. A thorough 360° shut-off mechanism helps extend the service life of the rubber liner.
<S-shaped disc (patented) structure that provides high sealing performance>
This disc uses a spherical face and an S-shaped disc developed by KITZ. When the valve is closed with a light torque, the entire surface contacts the sheet evenly, providing excellent sealing performance. The simultaneous all-round shutting function also contributes to a significant improvement in sheet durability.
