Parker B521ADH53C Double Solenoid Air Valve 4 Way 145 Psi

Product Description

The PARKER B521ADH53C is a 4-way, body ported solenoid air valve designed for directional control of compressed air in pneumatic systems. Configured with a double solenoid actuator and solenoid return, this 2-position valve operates on 120 volts AC and handles flow rates up to 88 CFM with a Cv of 1.4. Port connections are 1/4 inch inlet and 1/4 inch outlet. The valve is rated to a maximum working pressure of 145 psi (10 bar) and performs across an operating temperature range of 0 to 160 degrees F. Licensed HVAC technicians, pneumatic system integrators, and industrial maintenance professionals install this type of directional control valve in automated fluid-power circuits.

This valve is suited for use in pneumatic automation, machine control, and process equipment where positive 2-position directional switching of compressed air is required. Its body ported design routes air through the valve body rather than an external manifold, simplifying plumbing in panel-mounted or inline configurations. The NEMA 4 enclosure rating makes it appropriate for installations exposed to washdown or splash conditions in light industrial and commercial settings. Both residential and commercial pneumatic applications fall within its specified operating range.

Key Features

• 4-way, 2-position directional control with double solenoid actuator and solenoid return
• 120 VAC coil input for compatibility with standard control circuits
• 88 CFM flow rate with a Cv of 1.4 for responsive actuation
• Maximum working pressure of 145 psi (10 bar)
• NEMA 4 rated enclosure for use in wet or washdown environments
• Body ported design for simplified inline or panel-mount plumbing

Compatibility

Designed as an OEM-style replacement or direct-fit option for 4-way, 2-position body ported solenoid air valves with 1/4 inch NPT ports operating on 120 VAC in pneumatic directional control applications.

Installation Notes

Installation should be performed by a qualified pneumatic or industrial maintenance technician. Depressurize the system fully and de-energize all electrical circuits before removing or installing the valve. Verify that line voltage, port sizing, and pressure ratings match system requirements before making connections. Follow applicable OSHA lockout/tagout procedures and local electrical codes when wiring the solenoid coil leads.
