We plan to replace a pneumatic solenoid valve on [machine]. The valve is [full code / unknown], manifold [full code / unknown], and circuit/wiring drawings [number/revision]. Supply is [voltage and AC/DC]. Required operation and power-loss, air-loss and restart behaviour are [conditions / unknowns]. Main/pilot pressure and movement time/frequency are [conditions / unmeasured]. Please document ports and positions, coil count and actuation/reset method, pressure ranges, flow conditions, mounting face/seals, pin assignment/common/polarity and surge suppression. Separate body, base, connector, accessories and required modifications. State unresolved points, price, delivery assumptions and acceptance prerequisites. We will confirm the order after machine-side selection approval.
