If you have an urgent order, please contact us at +86 181 5720 5136. We will gather all the resources and check the possibility of fast production to provide clear feedback.

A: The wooden crates are used for transportation, which act as protective packaging during transportation, especially when products from multiple manufacturers are consolidated into one container for LCL transportation. This method can maximize their integrity.

A: 30% deposit in advance, 70% balance against the copy of B/L. T/T, Trade Assurance, Paypal, Western Union, Credit Card, L/C etc.

A: If you need to revise the product design or specification of cryogenic equipment, please let us know as soon as possible. We will work with you to understand the changes you require and provide a new design or specification that meets the need. Please keep in mind that depending on the extent of the revisions may impact the delivery timeline or pricing of the product.

A: If you need to cancel an order, please inform us as soon as possible. It's important to note that our production process begins immediately after we receive the deposit in our bank account. We have a buffer period of 1 or 2 days for returning the payment, which normally takes 1 or 2 days to get into our bank account. However, once the production has started, cancellation may not be possible and may result in cancellation fees or forfeiture of the deposit.

If you need to cancel your order, please contact us as soon as possible and provide the reason for cancellation. We will do our best to accommodate your needs while minimizing any impact on production timelines or costs.

A: A relief valve limits or controls the pressure in a system. It automatically opens at a set pressure and provides proportional and slow relief.

A: Yes, but this only occurs when the pressure exceeds the set level. During regular operation, pressures should not exceed the set level, and the valve should remain closed.

A: Maximum flow, maximum pressure, and the nature of the medium. Corrosive media might require different seals, diaphragms, or bodies. Ensure that the valve has the needed approvals for your application.

A: Yes, certain models can. To fully avoid water hammer, use a specific model that can accommodate both the high flow and pressure differentials common in a water hammer scenario.

A: Replace a relief valve if it leaks, shows corrosion or damage, fails to open at the set pressure, or is over 3-5 years old, based on manufacturer guidelines and conditions.
