Description
The FC-type flat gate valve is a type of one-gate valve as well as a full-bore gate valve. It can be used for double-flange, threaded-end and special connection configuration.
Pressure ranges from 2000 to 15000 psi and aperture sizes from 1-13/16″ to 7-1/16″.
In addition, it can be utilized with the actuator manufactured by Jiangsu GPZ.
Features:
■ Bi-directional downstream seal structure, improved servicelife;
■ Fixed metallic seal (between value plate and valve seat, and between valve seat and valve body);
■ Simple and reliable design for wedge disc and valve seat, which can reduce on-site service and minimize spare and accessory parts inventory;
■ Seal ring between valve seat and valve body can facilitate low-pressure sealing and prevent particulate contamination entering into valve body cavity and sealing area.
■ Valve stem seal design covers all pressure ratings, full temperature range and all possible fluid conditions in wellhead and manifold environment;
■ Metallic seal is applied between valve bonnet and valve body;
■ Valve stem’s rear seal structure allows for valve to be replaced when valve stem seal is under pressure;
■ In order to ensure safety, a grease injection device can be placed behind the valve stem’s rear seal and set on the valve bonnet to eliminate leakage into valve body;
■ Small switch working torque is easy to be turned on and off
