ACL Series 277 2/2 Way Normally Open Solenoid Valve

The ACL SS Servo Assisted Valves(NO) - Port Size 3/8 inch is part of the Series 277 range of servo-assisted diaphragm solenoid valves. This configuration uses a aisi 316 stainless steel valve body and a 3/8" connection, providing an electrically controlled on/off solution for compatible fluid circuits. ACL identifies Series 277 for applications involving fluid management and automated control, with the exact pressure and flow capability dependent on the selected connection and configuration.

Port-Specific Performance

For the 3/8" version, ACL documentation lists an orifice of 12 mm and a differential-pressure range of 0.15–15 bar. The 3/8" configuration has a documented flow coefficient of 2.2 m³/h.

Construction and Operation

The valve uses servo-assisted diaphragm technology. This type of construction uses the solenoid and pilot mechanism to control the main fluid passage, making it suitable for automated switching in systems where electrical control of a fluid line is required. The documented seal materials for this series are NBR / EPDM / FPM.

Key Features

• 2/2 Way Normally Open valve configuration
• Servo-assisted diaphragm actuation
• AISI 316 stainless steel body construction
• 3/8" connection for this product configuration
• Maximum fluid viscosity documented by ACL: 25 cSt (mm²/s)
• Preferred mounting position: preferably with coil upward

Applications

ACL positions Series 277 for industrial fluid control and applications requiring an AISI 316 stainless-steel valve body. Typical suitability depends on the actual fluid, pressure, temperature, seal selection and valve configuration, so the final application should be checked against the manufacturer's compatibility information.

Important Configuration Notes

ACL lists optional ATEX coils, food-fluid seals, slow-switching versions, oxygen-use versions and certified coils. Options should be confirmed against the exact ordered configuration. Coil voltage, coil power and seal selection are configuration-dependent and are therefore not assumed here unless they are explicitly specified by the product SKU.

Why Choose an ACL Servo-Assisted Valve?

ACL's servo-assisted valve range is designed for controlled fluid shut-off in automated systems. The combination of an electrically controlled solenoid, series-specific body materials and defined port/orifice combinations allows engineers to select a valve according to connection size, pressure requirements and fluid compatibility.
