Plug Control Valve Overview

Plug control valves are essential components in flow regulation systems, designed to operate with a 90° rotation to either connect or shut off the medium flow. The valve’s unique body cavity design features grooves and convex edges that securely hold the sleeve in place, offering enhanced performance in specialized applications. This design prevents simultaneous rotation of the sleeve and plug, a situation that could lead to valve damage during operation. The sleeve is made from high-quality Dupont PTFE, a material that is highly resistant to wear and tear, provides low friction, and offers reliable sealing capabilities, ensuring a long service life with reduced torque during operation.

Key Design Advantages of Plug Control Valve

The plug control valve’s innovative construction, featuring the PTFE sleeve, provides several important advantages:

Low Torque

The valve operates with minimal force required to turn the plug, reducing wear and improving efficiency.

Reliable Sealing

PTFE’s properties offer secure sealing, preventing leakage and ensuring optimal flow control.

Durability

The valve is built to withstand high pressures and temperatures, along with strong corrosion resistance, ensuring long-term performance in demanding environments.

Resilience to Harsh Environments

Our plug control valves are engineered to perform effectively in industries with harsh operating conditions. They are especially well-suited for environments where the medium can crystallize or contain granular impurities, making them an ideal solution for industries like petroleum, chemical processing, and smelting. These valves can withstand extreme conditions without compromising their functionality, making them an indispensable choice for critical applications.

Addressing Sealing Challenges in Large-Size Valves

Large plug valves, when built using traditional structures, often face challenges such as internal and middle sealing leakage over time. To overcome this issue, our advanced design features a self-developed trunnion-type double gland plug valve. This design innovation ensures better sealing performance and prevents leakage, even in large valves that endure prolonged use.
