Quick-fitting Type Mechanical Valve
Mechanical Valve
Features
This push-type valve turns on and off the input of air pressure.
The operating force is not affected by strength of pressure owing to the spool valve mechanism.
The valve has three ports to exhaust the residual pressure on the output side (equipment) when
closed and two ports that have no exhaust function.

Exhaust port
Exhaust port
In case of Three-Way, Normally Open type, the
compressed air entered from P port flows to A port.
While the spool is pushed down, the air inlet is blocked
and the residual pressurized air is released from the
exhaust port (open to air type or concentrated exhaust
type).
*Three-Way, Normally Closed type works contrary to
Normally Open type.

! Detailed Safely Instruction
Before using the PISCO device, be sure to read the "Safety Instructions","Common Safety Instructions for
Products Listed in This Manual" on page 23~24 and "Common Safety Instructions for Change Series Valves" on
page 279.
! Warning
1. Do not allow any load beyond the limit stroke to bear on the push pin or roller by maschine operation.
Otherwise damage to the body may result.
2. Do not use the valve with cam and dog whose operation involves steep leading and trailing edges. Impacts
may inflict damage to the device body.
3. Do not carry out the air switch or foot switch type of operation by a machine. Such an operation may
damage the device body.
4. In applications that require high level of reliability, make certain that the mechanical valve operates properly at
start-up.
5. Do not subject the product with a rotary resin body to forcible swinging or rotation. Otherwise the body may
suffer damage or develop leakage.
6. Do not use the valve in locations where it can be exposed to water drops, oil drops, dust, etc. The valve is
neither drip-proof nor dustproof, so that malfunction may result.

! Caution
Consult PISCO about applications involving frequent operations.
Confirm the number of ports and the conduction system by checking the marking on the body.
With the microswitch or the panel mounting type, the effective sectional area may change with the stroke.
Insufficient stroke may cause low flow rate.
With the air switch or the foot switch type, push the button or the top lid of the case completely until it stops.
Failure to do so may result in poor conduction or low flow rate due to faulty switching.
