API 6A Hydraulic Gate Valves

Hydraulic Gate Valves provided by CCSC are available in size from 1 13/16” to 7 1/16” and pressuring rating from 2,000psi to 15,000psi. the gate valves are strictly designed and manufactured according to API 6A and API Spec Q1 by forging or casting AISI 4130/4140 low alloy or AISI 410 SS steel, the actuators are designed with safety and suitable for all kind of gate valves.

CCSC Hydraulic Gate Valves' feature:

• 1. Forged or Cast Body & Bonnet,
• 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.
• 5. Easy maintaining and disassembling. 
• 6. Optional overpressure protection, compound-springs design for improving its stability.

Frac valves - ball screw gate valves 

Frac valves - ball screw gate valves provided by CCSC is a type of large bore gate high pressure valve which were improved from Cameron FLS-R gate valve, it's the main component of fr ac tr ee, the frac valve is often used on the top of the wellhead on high pressure oil well, can do the frac job for isolating the fluid from the well.

CCSC provides the FRAC VALVE was designed in accordance to API 6A and NACE MR-01-75, strict quality control conforming to ISO registration, This type of the frac valve contains flanged end, studded outlet, and special block body , both manual and hydraulic operation type can be supplied by CCSC, ball screw operation designed in manual type frac valve.

Features
• Forged Body and Bonnet. 
• Low operation torque under pressure. 
• Metal to metal sealing gate-to-seat and the seat-to-body. 
• Ball screw stem when manual operation. 
• Bi-directional FLS-R style slab gate valve for high pressure
• Flanged and studded outlet are available.
• The stem packing is a pressure energized seal and can resist severe Temp. and fluids.
• Critical application from 10000 psi to 20000 psi pressure.

Hydraulic Surface Safety Valve - SSV

Hydraulic Surface Safety Valve - SSV is designed to quick closure due to a pipe leak or burst, equipment malfunction, fire, or similar emergency.The Surface safety valve (ssv) is normally closed,pressure needs to be applied to the actuator to compress the spring and open the valve.

Hydraulic Surface Safety Valve feature:

• 1. Visual position indicator.
• 2. Optional fire protection (fusible loop).
• 3. Separate stems can make them easy disassembling and maintaining.
• 4. Has a compoud-springs designing to improve its stability.

The pressure needed to keep the valve open can be provided with a simple hand pump which, in an emergency, is bled off on the rig floor. However, a more sophisticated system called an emergency shut down (ESD) is recommended because it allows the actuator to be activated remotely.

CCSC designs and manufactures hydraulic actuator and slab gate valve,assembled safety valve with consideration of optimal safety and economic. The available safety valve sizes from 1-13/16" through to 7-1/16",of pressure rating from 2000psi to 15000psi.

Hydraulic actuator available specification

Line Pressure Operated Surface Safety Valve

Line Pressure Operated Surface Safety Valve is often used in the oilfield when need to monitors pressure in a flow line system, the system is compact and utilizes flow line pressure as the surface safety valve control medium. Utilizes well bore or pipeline pressure to operate actuator, if flowline pressure rise above or falls below set values, the system will sense the change and close the valve immediately
