Watts 115-2 TH 2 in Threaded Pressure Reducing Valve

SKU CH-YVW7-YEV3V

Threaded 2-inch pressure reducing valve handles 208 gpm continuous flow with pilot adjustment from 20 to 175 psi

  • Reduces pressure to a safe 20-175 psi range with adjustable pilot control
  • Handles continuous flow up to 208 gpm for reliable system performance
  • Withstands 400 psi operating pressure for durable service in demanding installations
  • Ductile iron body and Buna N elastomers resist wear up to 160 °F fluid temperature
  • 304 stainless steel nuts and 302 stainless steel spring provide corrosion-resistant operation

2-inch Threaded Pressure Reducing Valve

The Watts 115-2 TH is a single-chamber pressure reducing control valve designed for 2-inch threaded piping systems. It regulates downstream pressure in commercial, industrial, or municipal water supply installations where precise pressure management is required.

Flow Capacity and Operating Limits

The valve handles a maximum continuous flow rate of 208 gpm and a maximum intermittent flow rate of 250 gpm. It operates at inlet pressures up to 400 psi and accommodates fluid temperatures up to 160 degrees Fahrenheit. The pilot adjustment range spans 20 to 175 psi for outlet pressure control.

Construction Materials and Standard Constraints

The body and cover are constructed from ductile iron conforming to ASTM A536. Internal elastomers use Buna-N, while the nut and spring utilize 304 and 302 stainless steel respectively. Port sizes measure 1/2 in x 1/2 in x 1/4 in. The product carries a Proposition 65 warning for lead exposure.

Questions about this item

Will the 2-inch threaded connections match my existing iron piping?

The valve body is ductile iron ASTM A536 with 2-inch threaded ends, so it threads directly onto standard NPT pipe of the same size.

How can I verify the valve is regulating pressure correctly once installed?

Set the pilot between 20 and 175 psi, then check downstream pressure with a gauge while flow is between 208 gpm continuous and 250 gpm intermittent.

Does the package include pilot tubing or pressure gauges?

The valve ships with the ductile iron body, cover, Buna-N elastomers, 304 stainless nut and 302 stainless spring; pilot tubing and gauges are not included.
