Monitored Dual-Solenoid Air Valves

Part No. RCD-116 1/4" MONITORED DUAL-SOLENOID AIR VALVE (no pressure switch for fault diagnostics)

This three-way, 1/4" monitored dual-solenoid air valve is ideal for operating air cylinders on full-revolution presses. This dual valve is pneumatically checked. To assist in installation, this valve has a common electrical connector for both solenoids with a 12-foot cord. The Cv (flow rate) is 2.3 for the inlet port to the outlet port and 1.6 for the outlet port to the exhaust port.

Part No. RCL-551 1/2" MONITORED DUAL-SOLENOID AIR VALVE (no pressure switch for fault diagnostics)
(for 10- to 25-ton presses)

Part No. RCL-552 1/2" MONITORED DUAL-SOLENOID AIR VALVE (with pressure switch for fault diagnostics)
(for 10- to 25-ton presses)

Part No. RCL-553 3/4" MONITORED DUAL-SOLENOID AIR VALVE (no pressure switch for fault diagnostics)
(for 26- to 100-ton presses)

Part No. RCL-554 3/4" MONITORED DUAL-SOLENOID AIR VALVE (with pressure switch for fault diagnostics)
(for 26- to 100-ton presses)

This three-way cross flow, series/parallel air valve includes an air pressure electrical output monitor and muffler. Air is put into the clutch and brake when the dual-solenoid air valve is electrically energized. When it is de-energized, the air is dumped through the muffler from the clutch and brake.

This valve consists of two main parts: the piloted monitor assembly and the valve body assembly. The two main valve elements move simultaneously during normal operation. If these elements should fail to move simultaneously, the internal spool shifts; inhibiting further machine operation. The pressure switch (RCL-552 and RCL-554 only) will provide a signal to the control system to indicate a fault condition. A reset button on the side of the valve can be used to reset the valve if an accidental valve fault is detected.

The Cv (flow rate) is 3.0 for the inlet port to the outlet port and 8.0 (RCL-551 & RCL-552)/9.0 (RCL-553 & RCL-554) for the outlet port to the exhaust port.

Part No. RCL-555 1" MONITORED DUAL-SOLENOID AIR VALVE (no pressure switch for fault diagnostics) w/reset button
(for 101- to 300-ton presses)

Part No. RCL-556 1" MONITORED DUAL-SOLENOID AIR VALVE (with pressure switch for fault diagnostics) w/reset button
(for 101- to 300-ton presses)

Part No. RCL-557 1 1/2" MONITORED DUAL-SOLENOID AIR VALVE (no pressure switch for fault diagnostics) w/reset button
(for 301- to 1000-ton presses)

Part No. RCL-558 1 1/2" MONITORED DUAL-SOLENOID AIR VALVE (with pressure switch for fault diagnostics) w/reset button
(for 301- to 1000-ton presses)

This cross flow, series/parallel air valve includes an air pressure electrical output and muffler. The separate reset button provides a remote reset at floor level if the valve latches out when an accidental air valve fault is detected. This valve is used for the clutch/brakes on large presses which require larger air volume capacity.

This valve assembly consists of a pilot, monitor, valve body, and junction box. It operates on the same principles as the 1/2" and 3/4" valves described above.

The Cv (flow rate) is 8.5 for the inlet port to the outlet port and 19.0 for the outlet port to the exhaust port (RCL-555 & RCL-556).

The Cv (flow rate) is 21.0 for the inlet port to the outlet port and 43.0 for the outlet port to the exhaust port (RCL-557 & RCL-558).

NOTE: If the clutch and brake are split, two valves may be required to provide good stopping times.
