Direct Acting

Pressure Reducing Valve

CRD-L

Typical Applications

High rise buildings use CRD-L Pressure

Reducing Valves in various water systems

(potable water, boiler feed air conditioning, etc.)

to control pressure fluctuations between floors.

Industrial plants use CRD-L Pressure Reducing

Valves between a high pressure supply system

and equipment requiring lower pressure.

Typically CRD-L Pressure Reducing Valves are

used at supply connections for water heaters,

boiler feed water or other process water systems.

Municipal water systems use CRD-L Pressure

Reducing Valves at service connections in a high

pressure distribution zone.Depending on flow

requirements, CRD-L’s may be installed in

parallel. One CRD-L provides desired outlet

pressure while the second CRD-L handles low

flow conditions. If necessary, additional CRD-L’s

can be added for more flow capacity. The CRD-L

is also ideal for a low flow bypass around a larger

Cla-Val 90 Series Pressure Reducing Valve.

• Meets Requirements of

“Reduction of Lead in

Drinking Water Act”

• Operates in Any Position

• Easy Installation

• Stainless Steel Trim Standard

• Gauge Connections Standard

• All Bronze Body and Cover

The Cla-Val Model CRD-L Pressure Reducing Valve automatically

reduces a higher inlet pressure to a steady lower downstream

pressure with our unique design. This valve is an accurate regulator

capable of holding downstream pressure to a predetermined

amount, regardless of upstream pressure fluctuations.

Periodic maintenance consist of regular internal cleaning that is

accessed by removing bottom plug. There are no user serviceable

components.
