Description

Bolt cover, plug 90 degree around

Main structural features

Bolt cover, plug 90 degree around.

Its sealing is realized by the sealing face around the sleeve. It has unique 360 degree metal edge for protection and fixing of the sleeve.

There is no cavity in the valve for accumulation of medium. Metal edge provides the function of self-cleaning when the plug is rotated, applicable to the operation condition that is glutinous and apt to smudge, Double direction.

Sleeve Plug Valve FAQs

1. What is a sleeve plug valve or sleeved plug valve used for?

A sleeve plug valve (also called sleeved plug valve) is used for on‑off and throttling service in industrial pipelines. It provides bubble‑tight shut‑off and reliable operation in systems that handle clean, corrosive, or abrasive media.

2. What are the main advantages of a sleeved plug valve?

Its main advantages include cavity‑free design, low operating torque, good sealing performance, long service life, and minimal maintenance. The sleeve structure protects the plug and body while maintaining tight sealing even after repeated cycling.

3. What is a fluoroseal sleeved plug valve?

A fluoroseal sleeved plug valve is a non‑lubricated plug valve equipped with a fluorocarbon sleeve (often PTFE‑based) between the body and plug. It provides low‑emission sealing, high chemical resistance, and excellent performance in general industrial and chemical service.

4. What is a high-temperature sleeved plug valve?

A high temperature sleeved plug valve uses special high‑temperature sleeve materials (such as PFA, GF2P, HiTemp‑type formulations) to maintain integrity and sealing at elevated temperatures. These valves are designed for thermal cycling and harsh process conditions without cold‑flow or creep issues.

5. What is the difference between a sleeve type plug valve and a standard plug valve?

A sleeve type plug valve incorporates a full‑cylinder sleeve around the plug, which acts as a replaceable wear surface and sealing interface. This improves sealing reliability, extend service life, and simplifies maintenance compared with traditional plug valves that rely only on body and seat contact.

6. Do you have testing equipment in-house?

We own over 200 sets of modern testing equipment to ensure every valve is 100% qualified.
