FC valve

1. Full-bore design, effectively eliminate the pressure drop and eddy current, slow flow of solid particles in the valve.

2. The unique sealing, make the switch torque greatly reduced

3. Between bonnet & body and gate & seat are adopt metal to metal seal

4. Between gate and seat are adopt metal to metal seal, Surface spraying (heap) welding hard alloy , has good abrasion resistance, corrosion resistance.

5. Seat ring is fixed with plate, keep well steady

6. Stem has back seal structure so as to replace seal ring of stem with pressure

7. There is seal grease injection valve on bonnet side so as to repair seal grease , and provided seal and lubricate performance of gate and seat

8. It is match with all kind of pneumatic (hydraulic) actuator as customer's requirements

Expanding gate valve

1. Gate is fission expanding structure

2. Realizing low torque or low wear during switch

3. Between bonnet and body are adopt metal to metal seal

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 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 requirements 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.
