Key Product Features:

Reliable Quarter-Turn Operation: Allows for rapid and effortless opening or closing of the flow path with a simple 90-degree turn of the handle.
Blow-Out Proof Stem Design: The stem is mechanically retained within the valve body, preventing accidental ejection and ensuring maximum operator safety under pressure.
Secure Locking Mechanism: Features an integrated locking device on the handle to prevent unauthorized operation and maintain the valve in a safe, fixed position.
Low Torque & Long Service Life: The polished 304 stainless steel ball and high-quality PTFE sealing minimize friction, ensuring smooth operation and extended durability.
Rigorous Pressure Testing: Manufactured and tested to strict standards (2.4 MPa strength and 1.76 MPa sealing tests) to guarantee safety and leak-tight performance.

Applications:

Ideal for Municipal Water Distribution, Steam Distribution Networks, Oil Pipelines, and General Industrial Fluid Systems. Specifically suited for applications requiring a robust, cost-effective, and highly reliable isolation valve with built-in safety features.
