How it works
Opens and closes with a 90-degree rotation
It controls the flow rate by rotating the disc, and is quick and simple to operate.

Product Information
Key Features ( RUBBER & PTFE SEAT )
Rubber sheet (EPDM, NBR, VITON, etc.) seals the valve disc to ensure minimal leakage
(Bubble tight sealing).
(Bubble tight sealing).
Superior corrosion resistance and sealing properties compared to metal sheets.
Corrosion resistance is improved because the fluid does not come into direct contact with the valve body, but rather comes into contact with the rubber seat.
No separate gasket is required when connecting pipes.
