Lubricated plug valve manufacturers in Italy

Valvesonly Europe is one of the prominent Lubricated plug valve manufacturers in Italy, offers high-performance, long-lasting, and precision-engineered lubricated plug valves for various industrial uses.

Lubricated plug valve is one of the quarter-turn valves which is used for controlling fluid flow in high temperature and high- pressure applications. The valve consists of a cylindrical or tapered plug lubricated with a lubricant, which reduces the friction between valve parts, hence smooth operation and longer life. The valves have extensive applications across oil & gas, chemical processes, power stations, and water treatment.

Working:

The function of a lubricated plug valve is straightforward but very effective. In the closed position, the plug occludes the passage path, producing a tight seal against the valve body to eliminate fluid flow. In the opposite position, with the valve in the open position, the plug turns to put its passage into alignment with the direction of the flow, with fluid flowing freely through the valve.

This quarter-turn motion makes lubricated plug valves particularly suited to applications that need fast on/off operation or accurate flow control. Moreover, lubrication of the critical elements guarantees smooth operation over a long service life with lower maintenance and increased overall reliability.

What is a Lubricated Taper Plug Valve?

Lubricated taper plug valve is a high- performance plug valve where a tapered plug and lubricating system are employed to provide leak tightness as well as easy operation.

Taper Plug Design: Offers improved sealing than cylindrical plug valves.

Lubrication System: Injected lubricant minimizes friction and improves durability.

Best for High-Pressure Applications: Applied in oil & gas, steam systems, and chemical processing plants.

This kind of plug valve is favoured for use in critical services where leak-proof operation is vital.

How Lubricated and Non-Lubricated Plug Valves Vary?

A wear and friction-reducing lubrication system makes plug valves with lubrication suitable for high-pressure conditions.  By closing the space between the valve body and the plug, the lubricant prevents fluid from leaking.

The application of PTFE linings or elastomeric sleeves to minimize friction is the practice for non-lubricated plug valves.  They are less maintenance oriented and effective under low-pressure operation, but are expected to be worn out earlier in hostile surroundings than lubricated plug valves.

Functions:

Flow Control: Regulating, isolating, and redirecting fluid flow in pipes.
Leak Prevention: Tight, zero-leak sealing system.
High-Pressure Handling: Employed in the chemical processing, steam, and oil and gas sectors.
Long Service Life: The valve's lifespan is extended by the lubricating system.

Important Elements of a Lubricated Plug:

The valve body houses the lubrication and plug systems.
Fluid flow is controlled by a tapered or cylindrical plug.
Lubricant is injected via the Lubrication Injection System to lessen wear.
The sealing mechanism prevents fluid leaks.
Actuator/Handle enables automatic or manual operation.

Types of Lubricated Plug Valves:

Tapered Plug Valve: Includes a tapered plug for improved sealing.

Cylindrical Plug Valve: Employ a cylindrical plug for easy operation.
