Scroll down to learn more. How It Works Open: In the fully open position, the tapered plug is lifted all the way up. The slips are held to the plug via dovetails. Slips are fully retracted away from the valve body. In addition, the slips are protected from the flow. Closing/Rotating: Turning the handwheel clockwise begins to rotate the plug/slip assembly 90 degrees. During this rotation, slips maintain clearance from the body, therefore eliminating scoring/rubbing against the body during the full 90 degree rotation. During valve operation, the plug/slip assembly is held securely on centerline of the body by the use of large diameter upper and lower plug trunnions along with bushings installed in the bonnet and lower plate. Expanding: The plug/slip assembly has rotated 90 degrees and as the tapered plug begins to move downward, an expanding/wedging action begins to force the slips against the body seating area. Fully Closed : When the valve is fully closed and the slips are fully seated, the slip seal compresses into “as molded grooves” to provide a 100% variable Double Block and Bleed shutoff as well as secondary metal to metal firesafe seal for both upstream and downstream closure. The valve is bidirectional and does not rely on springs or flow for shutoff. DOWNLOAD BROCHURE DOWNLOAD INSTALLATION, OP. AND MAINTENANCE MANUAL Why It’S Better DOWNLOAD BROCHURE DOWNLOAD INSTALLATION, OP. AND MAINTENANCE MANUAL Superior Engineering: Designed as an improved version of the General Twin Seal Valve, the engineered valve was created to improve the integrity for double block and bleed valve applications. Longer Life and Less Maintenance: Greater slip retraction from body prior to rotation resulting in longer life and less maintenance. Superior Strength: Designed to have greater strength in lift and turn operation. Option for Top Mounted Actuator: Allows for faster operation and reduced cost. (Sizes 2”-12”) 100% Made in the USA: Many of our competitors buy their castings outside the USA and still claim their valve is made here. That is not the case with us. All our castings are supplied from North American foundries and all parts are machined and assembled at our facility in Bakersfield CA.
