Product Made In Japan
Manufacturer: KONAN ELECTRIC
Model: SSV2

This valve prevents accidents that may arise from a cylinder suddenly rising in response to the operation of a solenoid valve, etc. It has a built-in bleed mechanism to supply air to the cylinder gradually at the initial stage of operation of the cylinder, and by automatically opening the main valve at high speed when the pressure in the cylinder rises enough.

Operation

Standard type

When the cylinder has an internal pressure of 0 MPa: See circuit. When the three-position, open-center solenoid valve is placed in neutral and the directional control valve is OFF, the air pressures in chambers and of the cylinder are discharged through the solenoid valve, and the air pressure in the area flows to and is discharged. During discharge, the main valve of the slow-start valve is kept closed by spring force

To start the cylinder, activate the directional control valve by energizing solenoid number 2 to move the piston right. The air pressure then flows through passage 111, the drilled passage in the slow start valve’s piston, and finally into the cylinder chamber, increasing gradually. Install a needle valve between the chambers to adjust the air flow to the cylinder chamber, metering the cylinder’s control. This feature prevents the sudden operation of the cylinder. At the startup of the cylinder, the pressure on the piston top is still small, and hence the main valve of the slow start valve remains closed, as in the circuit.

During normal operation of the cylinder: Air enters the cylinder chamber through passages, and gradually increases. When the pressure reaches a given value, it starts to act on the piston top, pushing the piston down, and fully opens the main valve of the slow-start valve. When the main valve is opened, the normal air pressure circuit is completed. With a speed controller installed as the meter-out device, the cylinder speed can now be controlled.

Operating Instructions

1. Fluid

● Use only with clean fluids as dirt, wastes, etc. in the fluid may cause malfunctioning.

2. Starting speed of the cylinder

● Use the needle valve to adjust the starting speed of the cylinder.
