Key Features

WCB Carbon Steel Body

The valve body is manufactured from WCB cast carbon steel, offering high mechanical strength and excellent durability for demanding industrial applications. WCB is widely used in piping systems requiring long service life and reliable performance.

SS304 Stainless Steel Ball

The valve ball is made from SS304 stainless steel, providing excellent corrosion resistance and oxidation protection. Its precision-machined surface ensures smooth operation and dependable shut-off performance.

PTFE Seat

The valve is fitted with a PTFE seat, which offers excellent chemical resistance, high-temperature performance, and low friction. PTFE ensures reliable sealing and long-term durability under various operating conditions.

Double-Acting Pneumatic Actuator

The double-acting pneumatic actuator uses compressed air for both opening and closing operations. This design provides fast response, stable operating torque, and is ideal for continuous automated process control.

PN16 Flanged Connection

Standard PN16 flanged connections allow easy installation into existing piping systems while ensuring secure assembly and minimizing leakage during operation.
