Description

Instrument ball valve

Overview

Instrument ball valve is designed for on-off, high flow, high pressure applications. The one-piece trunnion mounted stem/ball eliminates the shear failure common in two-piece designs. Re-torqueable seat glands result in longer seat life and low friction stem seal reduces actuation torque and enhances cycle life. They can be operated safely up to 20,000 psi and up to 400°F, and up to 500°F with the high temperature option. 2-way, 3-way & 4-way switching and crossover styles are available.

Features

PEEK seats offer excellent resistance to chemicals, heat,and wear/abrasion.

Full-port flow path minimizes pressure drop.

316 cold worked stainless steel construction.

Low friction pressure assisted graphite filled Polytetrafluoroethylene stemseal increases cycle life and reduces operating torque.

Quarter turn from open to close with positive stop.
