Principle of Operation

Taylor Valve Technology Multi Orifice Valve design principle provides precision control. The two adjacent internal discs each contain two precision orifices.

The discs are lapped to within two light bands of flatness (+/- .00002”) to achieve positive shut off and maintain precise control. The fixed back disc is held perpendicular to the flow. The front disc floats against the back disc and seeks a mating surface promoting a positive seal. The differential pressure across the upstream disc and stabilizes the control surfaces. Vibration, noise or fatigues normally associated with loose or unsupported parts is eliminated. No control surfaces are introduced into the orifice, providing a clear center line for flow. The valves are rated for shut-off at ANSI Class III or IV depending on the style of valve and trim used. The orifices of the standard disc expose a small control surface profile to the fluid stream reducing wear. The multi-orifice design produces near linear flow characteristics. The low torque and quarter-turn design of Taylor Valve Technology’s Multi-orifice Valves allows for a variety of actuation options; manual, pneumatic, hydraulic, or electric.

Features

• Accurate control
• 90 Degree rotation from Full Off to Full On
• Bolted bonnet
• Safety bonnet is bolted into the body, it avoids the well-known risks of corrosion, cross threading, galling of threaded type connection in production environments.
• Safety body pressure bleed valve
• The potential for buildup or trapped pressure is eliminated by the installation of a high pressure stainless steel bleed valve installed in accordance with the requirements of API6A.
• Extended mean time between service
• Robust design and liberal application of hardened materials, efficient flow-geometry means the valves offer maximum production potential and minimum service requirements.
• Easy maintenance
• Choke valves are designed with special actuator mounting systems so the choke can be maintained.
• Optional features
• Choke valves can have trims and actuators custom designed for specific requirements, such as, special trims for noise reduction and sand control, reduced port and maximum orifice trims are available for very high pressure or minimum pressure loss for a declining field

Applications

• Well Site Automation
• Water Injection Control Valve
• CO Injection Control Valve 2
• Pump Bypass
• Pump Startup
• Gas Lift Injection Control
• Blow Down and Dump Valve
• Remote Control for directional drilling

 Series control valve features several unique design characteristics that minimize wear and maximize service life. One benefit is the cage and external sleeve trim. It is designed to contain turbulence and wear by centralizing the flow in the nozzle bore causing in stream flow impingement. The valve body and outlet are protected from wear because the energy conversion created by the pressure drop is contained in the trim cavity before flow enters the outlet. This eliminates the typical wear problems in the valve outlet. Another benefit is the balanced sleeve design. This greatly reduces the thrust required to lift the sleeve on and off seat as well as during throttling, making the control valve more user friendly.
