How it works.

Taylor Valve Technology, Inc. Multi-Orifice Valves (MOV) employ a simple design principle which affords precision control. The two adjacent internal discs each contain two precision holes (orifices). When the orifices on both discs are aligned, the valve is fully open. As the front disc rotates in relation to the fixed back disc, the flow area and available orifice size are reduced. When the front disc has rotated 90 degrees (one-quarter turn), the valve is fully closed.

The fixed back disc is held perpendicular to the flow. The front disc floats against the back disc and seeks a mating surface with the disc to assure a positive seal.

The differential pressure across the upstream disc promotes sealing, and stabilizes control surfaces. Vibration, noise or fatigue normally associated with loose or unsupported parts is eliminated.

The discs are lapped to within two light-bands of flatness (.00002) to achieve positive shut-off and maintain precise control.

The multi-orifice design produces near linear flow characteristics. No control surfaces are introduced into the orifice, providing a clear enter line for flow. The orifices of the standard disc exposes a small control surface profile to the fluid stream reducing wear.

The low torque and quarter-turn design of Taylor Valve Technology, Inc.'s Multi-Orifice Valves allows for a variety of actuation options: manual, pneumatic, hydraulic, or electric.
