Choke Va lves
Full Open Throttling Full 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 is either increase or decrease in flow.
When the holeson both discs arealigned the valve isin the Full Open Position.
When the front discis rotated a full 90o
(one quarter turn),the valve is in theFull Closed Position.
Taylor Valve Technology Multi-Orifice Valve Design Principle Provides Precision Control. The two adjacent internal discs each contain two precision orifices.
MOV Valve Principle of Operation
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 the downsteam disc stabilizes the control surfaces. Vibration, noise or fatigues normally associated with loose or unsupported parts are eliminated. No control surfaces are introduced into the orifice, providing a clear center line for the 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 steam 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 Body - Body is constructed with two bolted segments, avoiding the risk of corrosion, cross threading, galling of threaded type valve assemblies.
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 to provide simple straightforward disassembly with no special tooling or fixtures.
Optional Features - Choke valves can have trims and actuators custom designed for specific requirements, such as, special trims for noise reduction and sand control, several trims are available to accommodate high pressure flows or minimum pressure loss applications.
