Product Description

MAIN FEATURES
The sturdy one-piece ball and stem
provides optimal strength, and is well suited to applications where fouling due to coke fines are a concern. The one-piece design avoids the problems generally associated with the more conventional two-piece ball and stem, which is highly susceptible to solids buildup in the ball-stem joint and a resulting increase in operating torques.Avoids hysteresis and misalignment.

Design Features
A Lantern ring
with steam block and extra deep stuffing box minimizes the risk of leakage occurring through the packing chamber. Live-loading is available on request.
Strong bellows
offer a unique seat loading design that maintains the floating seats in constant contact with the ball and ensures a positive seal.
Velan's unique scraper type seats design
scrapes coke buildup from the surface of the ball during each cycle. Seats are hard-faced to ensure a long, trouble-free service life. 
Steam purges
to bellows and body area ensure the valve cavities are kept free of coke buildup.
The stem coupling
is designed to perform three main functions
Protect against "overtorquing" of the stem. 
Protect the actuator components.
Protect against an unintentional switch into bypass (typically applies to four-way switch).
Automation
The electric, hydraulic or pneumatic actuator is selected in function of coker service. A large torque safety factor ensures the valve will cycle under the most stringent conditions. When selecting actuators, special attention is paid to the coker deck environment.
