Product Use
Widely used in pipelines across various operating conditions in industries such as petroleum, chemical engineering, pharmaceuticals, fertilizer production, and power generation, for the purpose of cutting off or connecting the pipeline medium.
Product Features
· The valve operates without friction, resolving the issue of sealing failure caused by friction between sealing surfaces.
· The top-mounted design allows valves installed on pipelines to be directly inspected and repaired online, effectively reducing equipment downtime for maintenance and lowering costs.
● The single-seat valve design eliminates the risk of abnormal pressure buildup in the valve cavity, thereby ensuring operational safety.
· Low-torque design and specially structured valve stem allow the valve to be easily opened and closed with just your hand.
