What Is The Function Of Plug Valve In Different Industrial?

In processing plants, power stations, and pipeline networks, managing liquids, gases, slurries, and powders requires dependable valves. Plug valves offer simple yet customizable flow control to suit various industrial duties.

• Handle on/off, throttling, diversion applications
• Suitable for abrasive, viscous, high-pressure, hazardous media
• Used widely in chemical, petrochemical, oil and gas, and water industries
• Customizable alloys and linings handle demanding environments
• Compact, easy to automate control

In this article, we’ll overview valve with plug, their functionality, benefits, and applications meeting needs across sectors like oil and gas, water, chemical, beverage, pharma, and more. Their durable throttling and shutoff capabilities streamline production, transport, and safety.

Essential Functions 

Plug valves provide reliable on/off and throttling functionality. A cylindrical or tapered plug rotates inside the body, redirecting flow perpendicular to the seat. This enables quick, quarter turn operation from fully closed to fully open.

When partially open, flow passes through the valve smoothly. The fixed geometry avoids edges or tortuous paths that accelerate wear or product degradation. By incrementally turning the plug, precise flow regulation and diversion is possible without pressure drop.

Benefits include dead-tight shutoff, compact footprint, ease of automation, and low maintenance needs – making them a versatile workhorse across applications and industries.

What Is A Plug Valve Used For – Meeting Industry Challenges

Here are some of the primary applications of plug valves in various industries:

1. Chemical 

Plug valves constructed of corrosion resistant PTFE^[1], polyethylene, stainless steel and exotic alloys hold up to demanding chemical environments transporting acids, caustics, solvents, monomers, polymers, resins, and catalysts. High purity PFA linings prevent product contamination.

2. Oil & Gas 

Rugged plug valves handle onshore/offshore extraction and refining duties including gases, crude oil, multiphase streams, and byproducts like coke and bitumen. Fire-safe compliance ratings suit pipeline and facility protection systems.

3. Water

Water processing and distribution depends on tough plug valves movable parts resist abrasive media without excessive wear. Facilities optimize flow control system with pressure sealing valves engineered for longevity.

4. Power 

Flow regulation plays a crucial role in controlling steam, combustibles, water, and drainage. Tight shutoff prevents dangerous leaks with hazardous, explosive, or extremely hot fluids at electric plants and nuclear facilities.

5. Beverage 

Stainless steel plug valves enable clean precision flow in beer brewing, juice concentration, soda carbonation, dairy processing, and other sanitary food/beverage production without corrosion or contamination.

6. Pharmaceutical 

Compliant stainless and PTFE seals ensure product purity. Sterile environments are maintained for manufacturing parenteral serums, active pharmaceutical ingredients (APIs), vaccines blood derivatives, and intravenous (IV) mixtures.
