 Q1: What is the Warranty for the solenoid valves?
A1: For the valves,we have one and half year warranty.If any quality problems on our side during this period, we will make free replacement.

Q2: What is NO and NC?
A2: NO stands for normally open.While energized, valve closes; if de-energized, valve opens.NC stands for normally closed,While energized, valve opens; if de-energized, valve closes.

Q.3: What is the assembly way of solenoid valves?
A3: we suggest to make horizontal installation to enlarge life time,vertical installation is also ok if have special request.

Q4:ls there any cheap shipping cost to import to our country?
A4: For small order,express will be the best.And for bulk order, seal shipment is better but takes longer time.You can also make air shipment.

Q5:Can we make customized product?
A5:Yes, we are good at making solutions for customers. About 40% are customized products.Cooperate with top university in china,we have more than 20 professional engineers in solenoid valves. Our boss has more than 27 years experience in solenoid valve design.We have successfully made many excellent solutions for customers from china and abroad.
