Wilkins 212-ZW209BP Globe Style Pressure Reducing Valve With Low Flow By-Pass 2-1/2 in Nominal

Product Description

The WILKINS 212-ZW209BP globe style pressure reducing valve with low flow bypass prevents chattering of the main valve specifically from 0 to 10 gpm. It is designed for high inlet pressure reduction to stable outlet pressure in commercial and industrial water systems. Standard features ease maintenance and repair and provide the lowest total cost of ownership.

• Ideal for accommodating both high and low flow rates.
• Pressure gauges, wye strainer, isolation valves, and epoxy coating come standard to simplify start-up and maintenance.
• Holds downstream pressure to a constant value.

Product Highlights

This pressure reducing valve is ideal for maintaining constant downstream pressure, simplifying maintenance, and accommodating various flow rates.
