Control Valves for Oil and Gas Production export company - City Cat Oil Parts Supply
Control Valves

Control valves are used to control the flow rate, pressure or temperature in the process of oil and gas industry.

- Pneumatic globe type control valve
- Pressure reducing valve
- Electric globe type control valve

Butterfly Valves for Oil and Gas Production export company - City Cat Oil Parts Supply
Butterfly Valves

- Centric butterfly valves with soft seated, it used to cut off the flow like air, water, oil and other fluids. This type of butterfly valves have extended life cycles and lower cost of competing valves.
- High-performance butterfly valves are used to isolate and modulate a variety of media.
- Triple offset butterfly valves with blowout-proof stem and metal-to-metal seat, zero leakage performance. To make sure it suitables for extreme pressures and temperatures.

Ball Valves for Oil and Gas Production export company - City Cat Oil Parts Supply
Ball Valves

Ball valves are made out of several metallics whilst the seats are made from soft materials like Teflon. The combination of materials means the ball valve can operate at temperatures as low as -200 deg C and as high as 500 deg C.

Mainly used for air, gases and liquids, ball valves are quick to turn on and off and have a tight sealing with low torque. The only downside to these valves are the lack of throttling properties available.

- Trunnion-mounted ball valves
- Floating ball valves
- Full-welded ball valves

Check Valves for Oil and Gas Production export company - City Cat Oil Parts Supply
Check Valves

Check valves are used to protect mechanical equipment in a piping system by preventing reversal of flow by the fluid. This is particularly important in the case of pumps and compressors, where back flow could damage the internals of the equipment and cause an unnecessary shutdown of the system and in severe cases the complete plant.

Gate Valves for Oil and Gas Production export company - City Cat Oil Parts Supply
Gate Valves

Gate valves are primarily designed to start or stop a flow when a straight line flow of fluid and minimum flow restriction are needed. In service, these valves are pretty much kept either fully open, or fully closed.

When turned open, the disc of the gate is completely removed allowing contents to pass. Although this gives the valve good shut-off properties and is bidirectional, they cannot be quickly opened or closed and are sensitive to vibration when open.

Globe Valves for Oil and Gas Production export company - City Cat Oil Parts Supply
Globe Valves

Globe valves are typically used for cooling water systems, transporting fuel oil and turbine lube oil systems, a globe valve is a linear motion valve used to stop, start and regulate flow.

Conventionally used for isolation and throttling services, the globe has become the world's most common types of valves. With a good shut off ability, available in tee, wye and angle patterns and easy to machine the valve seats - its easy to see why they are so popular.

The slight disadvantages of the globe are that they perform unfavourably when high pressure drops, and require greater force or throttling flow under the seat to shut off valve.

Pressure Seal Valves for Oil and Gas Production export company - City Cat Oil Parts Supply
Pressure Seal Valves

Pressure seal valves are used for high pressure service, The unique feature about the pressure seal 'bonnet' is that the body's joints seals improve as the internal pressure increases. Pressure seal valves are typically used in excess of 170 bar.

Cryogenic Valves for Oil and Gas Production export company - City Cat Oil Parts Supply
Cryogenic Valves

Cryogenic valves design suitable for integrity pressure protection and emergency shutdowns in temperatures as low as ‒196° C.
