(Product Introduction
r
- The opening and closing parts of the imported internal thread gate valve are plug-shaped and the sealing surface of the valve disc is flat or tapered. The valve disc is in a straight line along the center line of the fluid. Movement. The movement form of the valve stem includes the lifting rod type (the handwheel for lifting the valve stem does not rise and fall) and the lifting and rotating rod type (the handwheel rotates together with the valve stem and the lifting nut is set on the valve body). The ribbed stop valve is only suitable for all-round valves. Adjustment and throttling are not allowed when opening or fully closing.<

The opening and closing parts of the imported internal thread gate valve
are plug-shaped valve disc sealing surfaces with flat or tapered surfaces along the center line of the fluid. Make linear motion. The movement form of the valve stem includes the lifting rod type (the handwheel for lifting the valve stem does not rise and fall) and the lifting and rotating rod type (the handwheel rotates together with the valve stem and the lifting nut is set on the valve body). When the stainless steel internal thread gate valve is opened When the opening height of the valve disc is <

of the nominal diameter, the flow rate has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the full opening height of the stop valve The open position should be determined by the stroke of the valve disc.
