Cla-Val Control Valves
Since 1936, Cla-Val has produced the world’s highest quality automatic control
valves for a diverse array of applications and marketplaces. The most common Cla-Valves
you will find in the waterworks sector are the
• 90-01 Pressure Reducing Valve
• 50-01 Pressure Relief Valve
• 50-90 Pressure Sustaining Valve

Cla-Val AQUA Air Valves
• Allows in air when draining the pipeline
• Allows air out when filling the pipeline
• Allows accumulated air out of pipeline under normal operation
• Anti-Slam controls air release under pump trip applications to safeguard the pipeline

Cla-Val X43H Strainer
The Cla-Val Model X43H Strainer offers an effective means of removing unwanted solid
particles in pipeline flow. These strainers are ideal for preventing fouling, debris and
particle build up in Cla-Val Automatic Control Valves. The large flow area design, with a flat
stainless-steel strainer mesh perpendicular to flow, is optimized for low pressure drop
applications.

Cla-Val Smart Valve Capabilities
When Cla-Val released the VC-22D Electronic Valve Controller, we knew it was a
game-changer. We understood immediately that we had designed a product with immense
potential.

In one small device that you can easily hold in one hand, the ability to control a multitude of
waterworks valve applications exists. Pressure Control with Upstream or Downstream
Feedback, Flow Control with Mag Meter or Electronic Flow Meter; Modulating Level
Control; Ratio Control; Altitude and Level Control; Logging; Pump Control and Pressure
Management are a few of the more common applications the VC-22D can control.

One common example of the VC-22D is paired with the Cla-Val Model 390-07 Electronically
Actuated Pressure Reducing Control Valve. The 390-07 is a Pressure Reducing Control
Valve with a Manual Hydraulic Bypass that combines precise control of field proven Cla-Val
hydraulic pilots with simple, remote valve control.

The 390-07 Pressure Reducing Valve automatically reduces a higher inlet pressure to a
steady lower downstream pressure regardless of changing flow rate and/or varying inlet
pressure. This valve is an accurate, pilot-operated regulator capable of holding
downstream pressure to a pre-determined limit. The valve uses a CRD34 electronically
actuated control pilot, consisting of a hydraulic pilot and integral controller that accepts a
remote set-point command input and makes set-point adjustments to the pilot.
