Benefits

long cycle life.
various materials of construction available for wide range of applications.
easy to maintain.
designed for control service with two-piece stem for highest cv.

Features

iso 5211 mounting pad for direct mounting of handle, gear operator, manual override, or actuator an extremely tight fit square drive between the stem and disc.
provides accurate and repeatable shut-off and control.
Bonded elastomeric cartridge seal is the most rugged method of construction available, providing consistent operating torque, maximum cycle life, and higher flow rates in control.
Avoids pinching and tearing that can occur with non-bonded seal designs.
Bonded elastomeric cartridge seal is easy to remove and replace if maintenance is ever needed.
Disc is precision machined with a spherical disc edge to provide long cycle life and consistent torque.
Two-piece stem arrangement for highest cv and maximum flow.
Top and bottom stems have anti blow-out protection that also prevents lifting or pushing of the disc during actuator installation or removal.
Lower stem includes groove for easy servicing.
The burnished stem is supported by self lubricating polymer bearings to minimize deflection and provide smooth operation and long life.
Every valve is factory tested, serialised & quality tagged prior to shipment.
