Can the blower be customized?

Normal blowers are standard parts, but voltage can be customized. Special treatments and IE2/IE3 standard blowers are also available upon request.

What is the loading time after order confirmation?

The loading time is 5-7 days after order confirmation and receipt of the deposit.

How should I install multiple valves for high-power blowers?

For high power, high flow, or double-stage high-pressure blowers (typically 12.5kw and above), you need to install 2 or more PVG1.25 valves.

Supplier typeThe supplier is described as a trading company in one record and as both a trading company and manufacturer/factory in another. Its stated business scope and factory address indicate involvement in manufacturing, but the records also confirm a trading-company classification.

CertificationsThe supplier explicitly states that it holds ISO 9001 certification for its management systems. This provides direct evidence of a formal quality-management certification.

After-Sales capabilityThe supplier states that it provides service, customized support, an 18-month warranty, fast delivery, and feedback within 24 hours. These claims indicate defined after-sales responsiveness and warranty support, although no independent service-performance records are provided.

Product Q&A

Q:What is the pressure adjusting range?

The adjusting range is 80-800mbar (8-80kpa). You can adjust the pressure by turning the screw plunger clockwise to increase or anti-clockwise to decrease.

Q:Can this valve be used for both pressure and vacuum?

Yes, it can be used for both. For positive pressure (outlet), the arrow should point up. For negative pressure (inlet/vacuum), the arrow should point down.

Q:How does the pressure relief valve work?

When pressure exceeds the spring's deformation force, the sealing sheet opens to release excessive volume, protecting the blower. It closes slowly when pressure drops to a safe value.

Q:What is the warranty period for the blower?

We provide an 18-month free warranty period and lifetime maintenance for the blower.

Q:How long is the expected life of the blower?

Under normal conditions, the blower life is 3-5 years.
