Plug Valve Manufacturer in USA – SVR Global
SVR Global is a specialized Plug Valve Manufacturer in USA, delivering robust solutions for industries that demand tight shutoff and reliable performance. Our plug valves are engineered for isolation and throttling in oil & gas, petrochemical, water treatment, and power generation services. Designed to meet API 6D, ASME B16.34, and MSS-SP standards, our valves ensure long service life even in abrasive and corrosive conditions.
Function & Working
Plug valves operate by rotating a cylindrical or tapered plug with a passage to align or block the flow. This quarter-turn mechanism provides bubble-tight shutoff and low-pressure drop. Options include lubricated, non-lubricated, and pressure-balanced designs to suit varying service conditions.
Advantages
Quick quarter-turn operation
Suitable for slurries and high-solid media
Tight sealing even under high pressure
Low maintenance and compact design
Available in full port or reduced port designs
Types Offered
Lubricated Plug Valve – Pressure-balanced designs with sealant injection system
Non-Lubricated Plug Valve – Uses sleeve or liner for smooth operation without sealants
Eccentric Plug Valve – Ideal for wastewater, sludge, and abrasive applications
Jacketed Plug Valve – Maintains process fluid temperature (steam jackets)
Multiport Plug Valve – Designed for diverting and mixing services
Industries Served
Oil & Gas
Petrochemical & Refining
