Definitive model of constant flow regulator with variable flow rate setting

	Excellent constant flow characteristics
	With the built-in control function, the designated flow rate can be maintained automatically regardless of changes in primary pressure, and the flow rate can be set easily with the handle. It is an excellent variable constant flow regulator.
	Extremely low operating torque
	Due to the unique balancing mechanism, the flow rate setting operation can be done with low torque regardless of water supply pressure. This enables application of a small electric actuator instead of manual operation, and even makes economical application of a solar-powered system possible.
	Simple direct-operation regulator valve
	This simple direct-operation regulator valve does not use complicated pilot valves and is therefore clog-resistant.
	Cavitation characteristics
	Due to the unique pressure reducing mechanism, the allowable cavitation coefficient can be set extremely low.
	Flow rate control characteristics
	Lift type construction of the built-in adjustment valve enables nearly linear performance in flow rate control.
	High-performance
	This automatic regulator valve has both constant flow control and flow rate adjustment functions, so it is easy to handle and suitable for various applications. To ensure durability and reliability, the main parts are made of corrosion and wear resistant materials.
	Demonstrated performance
	Excellent performance as verified by the National Research Institute of Agricultural Engineering of Japan.

YOKOTA's proposal for economical piping units Cost reduction in piping units is possible by using the YOKOTA Constant Flow Regulator Valve For example, when supplying cooling water to the engines at rainwater drainage plants, a piping system with an electric ball valve unit and a constant flow valve unit set in a series is generally used. But, it is possible to simplify this system into a single unit by using the YOKOTA Constant Flow Regulator Valve. This is because the YOKOTA Constant Flow Regulator Valve not only has a function to control constant flow, but also functions to adjust the required flow rate from the outside and to shut off the flow. (Example) Comparison with a conventional system when cooling 1050HP engines. (Calculated by the user) 1. Cost: Approx. 50% reduction 2. Space for installation: Approx. 50% reduction 3. Adjustment of flow rate is possible at installation site
