Description

API 6A 2-1/16in 5000psi Pff Plate Gate Valve

Gate Valve is used to open or close the pipeline. According to the structure, the gate valves is distributed into rising or non-rising stem gate valve. According to the mode of operation, it is distributed into manual or hydraulic etc. The gate valve is used for drilling fluid manifold, choke manifold, kill manifold and Christmas tree etc.

The plate gate valve is the main component of the Christmas tree, the tubing head, the casing head and the manifolds. It is one of the major products manufactured by camtop. In recent years, by making use of advanced technology both at home and aboard, camtop has developed an innovated quite a few new designs of the value in terms of products structure and material selection. The products are all manufactured, checked and accepted as per API Spec 6A standard.
Features: 

(1). Sealing for body and cover is metal to metal seal, improve the sealing performance.

(2). Stem and cover designed with backseat sealing structure is easy to take pressure change valve stem packing.

(3). The body is made of high quality alloy steel steel forgings, no perforation design, safe and reliable.

(4). Sealing surface spray weld hard alloy, with corrosion resistance, resistance to erosion and wear resistance performance.

(5). Body pad ring groove can according to user’s requirement overlaying austenitic stainless steel, improve the corrosion resistant ability to enhance its service life.

(6). Use spring preload load in the disc and seat, completely realize two-way seal.
