Product Overview

The CLA-VAL 43E/D-01: Flow Control Valve with Solenoid Shut-Off is designed to deliver a constant flow while opening or closing remotely. This advanced valve's solenoid can be activated by an electrical signal from a timer or programmer, such as e-Smart/L1. It is also uniquely employed to significantly increase flow in a downstream area when a fire occurs, demonstrating its critical role in safety systems. As part of the CLA-VAL SERIES 40, this valve accurately limits excessive flow to a preselected maximum rate (Flow Control) regardless of changes in pressure or varying inlet flow. It offers completely automatic, simple, reliable, and accurate operation.

Key Benefits

• Remote & Automated Flow Control: Designed to deliver a constant flow while enabling remote opening or closing via electrical signals from a timer or programmer.
• Fire Protection Capability: Can be activated to significantly increase flow in a downstream area during a fire event, serving a vital safety function.
• Scheduled Flow Delivery: Capable of delivering a constant flow at fixed hours during the day when integrated with a timer, ideal for scheduled operations.
• Accurate Flow Limitation: Accurately limits excessive flow to a preselected maximum rate, ensuring consistent performance regardless of pressure changes or varying inlet flow.
• Automatic Operation: Provides completely automatic, simple, reliable, and accurate performance.
• Quality Approved Materials: Manufactured with quality-approved materials, ensuring durability and long service life.

Applications

The CLA-VAL 43E/D-01 Flow Control Valve with Solenoid Shut-Off is suitable for a variety of critical flow control applications, particularly those requiring remote operation, scheduled delivery, or fire safety integration:

• Remote control of water flow in distribution systems.
• Automated irrigation or water delivery systems with timed operations.
• Fire protection systems requiring increased flow in emergency situations.
• Applications where accurate limitation of excessive flow is necessary.

Features & Construction

• Solenoid Control: Available as 311-D or 311-C.
• Flow Control: CDHS-18.
• Orifice Plate Assembly: X52-A (included) for controlling flow rate and preventing cavitation.
