- The Pilot Operated Pneumatic Valve range covers 4V and SY series for pneumatic control in industrial automation machinery.
- 4V models follow an AirTAC-type structure, while SY models follow an SMC-type structure.
- Buyers can match the required series to the valve family already used on the equipment before confirming the individual model.
Voltage Confirmation
- The 4V series supports 24V, 36V, 110V, and 220V options for different control-power requirements.
- Listed models are 4V210-08, 4V110-06, 4V310-10, SY3120-5L, and SY5120-5L.
- The main construction uses an aluminum-alloy valve body with a copper coil and anodized surface treatment.

Custom Reference Route
- Zhejiang Yangtian Pneumatic Technology Co., Ltd. supports OEM/ODM production from customer technical drawings or physical samples.
- For non-standard products, MOQ and sample-development time depend on the specific model and structure.
- A sample may be supplied before batch production where additional confirmation is required.

Inspection Before Packing
- Incoming materials are inspected before production, and manufacturing follows the applicable process requirements.
- Key work positions receive in-process checks. Finished valves are tested for sealing, operating performance, pressure resistance, and durability.
- Sampling inspection is performed before packing, and buyer-arranged third-party inspection is accepted.

Order Assembly
- Small products use individual boxes. Larger units receive bubble protection before carton packing, with woven bags and packing straps added externally.
- Standard delivery timing is reviewed according to order quantity; customized production depends on specification, model, and volume.
- Samples are available before a larger purchase.
- For a Pilot Operated Pneumatic Valve quotation, provide the series, exact model, required 4V voltage where applicable, quantity, and any non-standard production reference.
