An alternative to the original two-valve system, the GENERAL VALVE Twin Seal plug valve has just one double-seated bubble-tight valve. The upstream and downstream seals provide the same function as the two block valves. The body serves as a spool piece and the body bleed verifies seal integrity.\u200b<\/p>
Seal abrasion is inherent in the design of most ball and gate valves. In most instances, the seats are ground or wedged against metal every time the valve cycles. Any foreign material lodged between the seats and ball or gate will score the seating surfaces. Once the seating segment is scored, product loss and contamination result. The GENERAL VALVE Twin Seal plug valve avoids abrasion by having both independent slips completely retracted from the body bore during cycling.\u200b<\/p>
The GENERAL VALVE Twin Seal plug valve\u2019s completely retracted slip design minimizes leakage risk, reduces wear and maintenance, and saves money.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
