Principle of Operation

Full Open Throttling Closed

When the front disc is rotated,changing the alignment andrelationship to the fixed back disc,the flow area and orifice size areaffected, the result either increaseor decrease in flow.

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

When the holeson both discs arealigned the valve isFull Open Position.

When the front discois rotated a full 90

(one quarter turn),the valve is in thefull closed position.

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.

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, efficien

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
