The sleeve-type plug valve is an improved form of the traditional plug valve. It keeps the fast quarter-turn action and solves the traditional problems of poor sealing and high ope

Fully jacketed sleeved plug valves is mainly used in pipeline systems of chemical, petroleum and pharmaceutical industries, especially for conveying viscous, solidifying and crysta

The fully jacketed sleeved plug valve is a valve that integrates sleeve design into the standard sleeve stopper valve structure. It is mainly used to transport and control media wi

The check valve is the only valve without a manual actuator. Forward flow lifts the disc; when flow stops or reverses, the disc reseats by its own weight, spring force, or back pre

The fundamental distinction between floating ball valves and trunnion-mounted ball valves lies in which component executes the sealing action. In a floating ball valve, the ball is

The packing gland is the critical dynamic seal in control valves. A failure here not only causes environmental and material losses but also poses severe safety hazards. 1. Packing

A spiral wound gasket combines the elasticity of metal with the plasticity of soft filler materials. It is constructed by alternately winding V-shaped metal strips and soft filler

The V‑Port Reshapes the Flow‑Opening Relationship A V‑port ball valve incorporates a narrow‑tipped notch in the ball, which fundamentally alters how the flow area evolves with rota

In recent years, SIL certification has been increasingly specified in valve procurement technical documents. The following summary addresses key concepts, parameters, and implement

In modern industrial automation, compressed air often carries moisture, oil, and dust. As a critical front-end component, the filter regulator protects downstream precision equipme
