“Appex” gland type two piece / three piece / single piece design flange end ball valves are being constructed with all genuine working parts and giving guaranteed performance of 100 % tight shut off working. These super finished products ensure long life performance, low operating torque and striking performance. Design data of “Appex” gland type ball valves comply with latest relative international standards. All accurate and precise working through machining and assembly drawings are making really good and preferred quality products. Wide variety of materials of constructions can be offered for “Appex” gland type ball valves for particular range described in this catalog. These unique design valves have taken reputed place to many process industries due to some significant features like :


“Appex” ball valves bonnet is provided with an integral cast ISO 5211:2008 mounting pad for ease of automation. Pneumatic actuator or gear box unit can be fitted on actuator mounting flange with drilled and tapped hole without any modification in fitted valves.

Gland :

Investment casted gland is fitted with bolts on ISO 5211 mounting pad. 100 % fugitive emission free results can be obtained by tightening gland. Well tightened gland compressed gland packing uniformly at specific elasticity point and ensures desired long life air tight sealing . Gland also supports to reduce thrust loads as well as operating torque.

Locking arrangement :

Sheet metal cutting stopper plate is designed for dual purpose. One, it turns quarter from open to close position while operate valve. Second it can be locked with gland or ISO pad to prevent valve operating without permission or unauthorized operating.

Square stem and lever :

Close integrity between stem and lever is obtained by square design. Without thread heavy duty stainless steel stem gives easy operating with lower torque. Accurate made square insertion on lever provides desired integrity. Long life operating cycles can obtain with this unique design and removes chances of deformation in lever and stem.
