PFF series parallel gate valves are manufactured in strict accordance with API Spec 6A. It has reasonable structure, small opening torque, good sealing performance and good corrosion resistance. Can be used as wellhead device and various pipe manifold components

Valve body as the core parts of gate valve, is the most important pressure parts, directly determine the safety and reliability of the whole set of valves.

The valve body adopts the integral forging molding, can obtain the denser internal organization, the metal streamline integrity, the organization optimization, achieves the better mechanical performance and the longer service life, the safety, the reliability, and the appearance is beautiful, the manufacture cycle is short, the strength is high.

• 1. Forged or Cast Body & Bonnet, A wide range of body and trim materials to meet various operating conditions.

• 2. Metal-to-Metal seal, gate to seat, seat to body, bonnet seal and stem backseat.

• 3. Bi-directional Sealing,

• 4. All internal parts can be inline changed,No special tools are needed to change gate and seat assembly.

• 5. Heavy duty thrust bearing is used to absorb stem thrust and reduce operating torque.

• 6. The Stem pin protects the stem and internal parts from failure by shearing if the handwheel is over-torqued
