Liner Locking

The lining is securely locked into the deep machined groove slot into the body & holes in casting ball under melting processible of FEP or PFA. This prevents liner to collapse or blow out under full vacuum/high pressure/temperature applications.

Integral Ball & Stem

Encapsulated one PC design ball & stem. No possibility of rupture of ball & stem joint. Ensure trouble free frequent operations.

Two PC Design Body

Two PC Design Bolted Body Construction with Stainless Steel Fasteners, minimize the joint leakages.

Low Torque Operation

The contact area (sealing area) of ball with seat is very less, thus operating torque is much lower than the plug valve. Lever is compactly designed to operate the valve with very low torque. The valve above 4” size are offered with worm gear box actuation for smooth operation.

Standard Design

The “Briflon®” fully lined ball valve are designed in accordancewith flange dimension of ANSI B16.5, & face to face dimension of ANSI B16.10 permits these valves to replace with any standard ball valves without altering existing piping.

Full Port Design

Minimize the Pressure drop and increase the flow capacities
