Characteristics ofYP TYPE GATE VALVE :

YP Type Gate Valve adopts the structure of stemvisible plus tail-rod to effectively maintain the pressure balance inside the valve cavity.

     This product can be used in an extreme bad condition. Therefore, it can be adopted in the control system of BOPS.

The stroke of the piston is limited by the cylinder bonnet or valve bonnet. So, there is no excess pressure applying to valve stem or valve gate. This kind of design can extend the valve working life.

Characteristics of PW TYPE GATE VALVE:

PW Type Gate Valve is designed in a stem-visible structure. There is a remarkable sign for the vale stem coming out and going in. A tail rod is additional on the valve tail end to play a balance function.

   A high performance wave-shaped spring is used between the valve body and the valve seat. This structure can ensure a good seal function between valve gate and valve seat even if in a low pressure condition.

The valve gate packing is all import rubber. The products have a high capability of packing performance, long working life, less opening and closing torque.

Technical criterion in design and manufacturing for this series gate valve API Spec 6A.
