CONFIGURATIONSCONFIGURATIONS

rate and/or varying inlet pressure

- Model 6115-JM Pressure

Reducing Control Valve

- Designed to reduce a higher, fluctuating
inlet pressure to a constant, lower,
outlet pressure

- Flow range: 30 gpm – 580 gpm

- Downstream pressure adjustment
range: 30 psi – 300 psi

- Automatically reduces higher inlet
pressure to constant lower outlet
pressure regardless of changing flow

- Model 6115-7JM Pressure Reducing

and Downstream Surge Control Valve

- Constructed same as the 6115-JM with
additional downstream surge control pilot

- The added surge control pilot ensures positive
pressure control when downstream high
demand equipment operates causing potential
water hammer

- Flow range: 30 gpm – 580 gpm

- Downstream pressure adjustment
range: 30 psi – 300 psi

Control Valve with Low-Flow By-Pass

- Constructed the same as the 6115-JM with
addition of a full 3/4" Low-Flow By-Pass,
expanding the flow range

- Flow range: 1 gpm – 580 gpm

- Downstream pressure adjustment
range: 30 psi – 300 psi
