FAQ

Q: What type of diaphragm used in oil media?
A: Usually, Nitrile, Viton, PTFE, and EPDM diaphragms are applicable in oil media.

Q: I have been told that 2-way valves only allow fluid flow in one direction is it correct?
A: Generally, 2-way valves allow fluid according to the cylinders. If there is a single-acting cylinder fluid flow in a single direction when a double-acting cylinder being used, fluid is able to flow in both directions.

Q: I am looking for a valve factory for a long term business relationship. What product you main specialized?
A: We've been in valve field since 2000s, mainly for solenoid valve, motorized valve and pneumatic valve, the lever valve provided
also.

Q: I have a drawing for customized valve, can you do it?
A: Sure, we have our own CNC machine. No matter curved surface or complex process can be finished.
 

Q: Do you have stock for RTS?
A: Conventional products are fully stock on warehouse, once you place order, it will be send out in 1 day.

Q: We are concerned about the technical support after using your product. Any technical engineers can be provided?
A: Yes, our engineer 24 hrs online once you contact.

Q: What methods of payment do you accept?
A: T/T, Paypal and credit card can be accept.

Q: Can my order be expedited?
A: Yes, after you've added items to your cart you can calculate expedited options for your order. You can also call us for a
shipping estimate.

Q: What is the difference between a direct acting solenoid valve and a solenoid- pilot operated valve?
A: In a direct acting valve, the main body or poppet is moved using magnetic force generated by the electrical coil to shift the
valve. In a solenoid-pilot operated valve, the main body or plunger is moved using force developed from the available pilot
pressure. The coil in this case is used to control the pilot for the pilot piston.

Q: How many materials can be used apply to solenoid valve from COVNA?
A: Stainless steel 316L(Sanitary grades), Stainless Steel 316&304, Brass and cast steel.
