aylor Valve MDI / MDIS Series Chokes are made with wear resistant material to extend service life, with redundant O-Rings on the Bonnet Seals andStem Seals that help prevent leakage. Fully GuidedStems reduce imbalance and vibration. ControlDiscs provide ANSI Class III/IV Shut off. Available sizes are the 1 Inch, 2 Inch, and the 3 Inch chokes.

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.

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 - Repair parts can be installed in the field without removing the valve from the line.

Optional Features - Choke Valves can have trims and actuators custom designed for specific requirements. Such as special noise reduction trims, reduced port and maximum orifice trims, and for very high pressure or minimum pressure loss for a declining field.

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.
