What is the advantage of non lubricated sleeved plug valves over conventional lubricated plug valves?

Non lubricated sleeved plug valves use a PTFE or elastomer sleeve that provides sealing without sealant injection. This eliminates contamination risk, reduces maintenance costs, and ensures consistent performance in clean or corrosive services.

Can these valves be supplied with jacketing for steam tracing?

Yes, Valve Industries offers partial and full jacketing options for both plug valves and ball valves. This is essential for applications involving viscous fluids, molten sulphur, or products that solidify at ambient temperatures.

What materials are available for corrosive chemical service?

Body and trim materials include Alloy-20, Duplex Stainless Steel, Hastelloy B, and Hastelloy C for handling acids, chlorides, and other aggressive chemicals. CF8M (SS316) is suitable for moderately corrosive applications.

Are actuator-mounted versions available for automated control?

Yes, all valves can be supplied with pneumatic, electric, or hydraulic actuators. Gear operators are available for larger sizes requiring manual operation with reduced torque.

What is the difference between L-port and T-port in 3-way ball valves?

L-port allows flow between two of three ports at a time (diverting service), while T-port can connect all three ports simultaneously (mixing service). Selection depends on whether you need flow diversion or mixing functionality.

Overview

Valve Industries, established in 1969, manufactures a comprehensive range of non lubricated sleeved plug valves and full bore ball valves designed for demanding industrial process applications. These valves are engineered for reliable shut-off and flow control in chemical processing, petrochemical, pharmaceutical, and general industrial plants.

The non lubricated sleeved plug valve design eliminates the need for sealant injection, reducing maintenance requirements and preventing process contamination. Available in taper port (regular bore and full bore) configurations, these valves suit applications where zero leakage and extended service life are critical.

Ball valves from Valve Industries feature full bore construction in 1-piece, 2-piece, and 3-piece designs, offering flexibility for installation and maintenance. Multi-way configurations (2-way, 3-way, 4-way) enable flow diversion and mixing applications without additional piping complexity.
