Product Benefits
Reliable Double Sealing
The valve features sealing grooves with sealing rings on both the inlet and outlet sides. As pipeline pressure changes, the sealing force automatically adjusts to maintain reliable leak-tight performance. Consequently, the valve provides dependable sealing under varying operating conditions.
Low Operating Torque
The PTFE sleeve significantly reduces friction between the plug and the valve body. In addition, the PTFE diaphragm, O-ring, and gasket work together to minimize operating torque while maintaining excellent sealing performance. Therefore, valve operation becomes smoother and more energy-efficient.
Longer Service Life
Unlike conventional plug valves, the PTFE sleeve is securely retained inside the valve body to prevent displacement caused by pressure or temperature fluctuations. This design minimizes wear and extends the sealing life of the valve.
Self-Cleaning Performance
During every opening and closing cycle, the metal edge of the plug continuously wipes the sealing surface clean. As a result, deposits and sticky materials are removed automatically, allowing the valve to perform reliably even in dirty or viscous media.
Flexible Installation
The valve supports bi-directional flow. Therefore, installation is more flexible because there is no strict flow direction requirement.
Structural Features
The valve features a compact, heavy-duty design that is well suited for continuous industrial service.
Its PTFE sleeve completely surrounds the plug, providing dependable sealing while reducing friction and wear during operation. Furthermore, the valve body contains no internal cavity where process media can accumulate. This design minimizes contamination, simplifies cleaning, and reduces maintenance costs.
The valve is engineered for high-pressure service and frequent operating cycles. Depending on customer requirements, body materials, trim materials, flange standards, pressure ratings, and actuator configurations can all be customized.
