شیر پروانه ای کارتریجی با نشیمنگاه لاستیکی در WCB

The cartridge rubber seated butterfly valve in WCB is widely used in water supply, HVAC systems, fire protection, and general industrial services due to its compact structure and reliable sealing. The “cartridge” seat design allows for easy replacement of the rubber seat without removing the entire valve from the pipeline, making maintenance quicker and more cost-effective. The rubber seat provides tight shutoff even under low pressure, reducing leakage risk. Constructed with a WCB (Weldable Cast B-grade carbon steel) body, the valve offers excellent strength and durability, making it suitable for medium-pressure applications and capable of withstanding harsh working conditions. Its lightweight, quarter-turn operation and cost-efficiency make it a preferred option for on-off and throttling service. This type of valve is particularly useful in systems where downtime must be minimized and long-term performance is critical. Regular inspection helps ensure optimal function and extends its service life.
