Plug Valve Types

 

Sleeved Plug Valves:

Utilizes a non-metallic sleeve inserted into the body cavity to eliminate cavity pockets, minimize operating torque, and provide bubble-tight sealing without sticking.

Lubricated Plug Valves:

Designed with internal channels that distribute sealant between the plug face and body seat, ideal for high-pressure service or abrasive media requiring assisted sealing.

Sleeve Type Plug Valve

Non-Lubricated Plug Valves:

Engineered for applications requiring clean operation and minimal routine upkeep, eliminating the need for periodic grease injection.

Three-Way Plug Valves:

Configured with multi-port pathways to facilitate efficient fluid diversion, stream merging, and directional distribution across complex piping loops.

Product Advantages

Durable Material Selection:

Base metals and internal trims are selected according to fluid chemistry, mechanical load, and thermal exposure to maximize longevity in hostile environments.

Efficient Flow Control Design:

The low-torque quarter-turn mechanism allows rapid opening and closure, while the streamlined flow path minimizes pressure drop across the valve.

Manufacturing Process
 

Precision Machining:

Advanced computer numerical control equipment shapes valve bodies and plugs to tight dimensional tolerances, ensuring uniform assembly and reliable seat contact.

Assembly & Testing:

Every valve is hand-assembled in clean environments and subjected to shell and seat testing to verify structural integrity prior to packaging.

Process Control:

Quality checkpoints govern raw material chemistry, machining dimensions, torque measurement, and final visual verification.
