1 Features The heck Valve permits the air flow in one direction but checks the flow in the opposite direction, thus keeping the output pressure at a constant level. The heck Valve can keep the service pressure at-750mmhg (vacuum) and permits piping under low pressure. onstruction Graphical representation Quick Fitting Type heck Valve heck Valve elease ring (polyacetal) Tube ock claw (stainless steel) Metalic body (nickel-plated brass) lastic sleeve (nitrile rubber) Holder (aluminum) O-ring (nitrile rubber) Specitication Fluid admitted Service pressure range Operating pressure Working vacuum Service temperature range 0~0psi 1.5psi -.95 in.

19 ! Detailed Safely Instruction efore using the PISO device, be sure to read the "Safety Instructions","ommon Safety Instructions for Products isted in This Manual" on page 3~ and "ommon Safety Instructions for hange Series Valves" on page 79.! 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.. 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.. 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.. 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 ! aution onsult PISO about applications involving frequent operations. onfirm 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. 93
