ProductName：Double type check valve 

ProductNumber：HL7B000

Overview

The structure of double type check valve is advanced and reasonable, the flow rate is little, weight is light, compact conformation, costs are cheap, and installation is convenient. Switch is flexible. Leak tightness is very good. It is particularly suitable for compressor road, of heat exchanger, gas station, irrigated area, thrust jet, oil products’ transportation and waste water, steam, various pumps etc.

Function:

Prevent medium from reverse flowing. It plays the role of recloser.
Prevent the equipments, environment and body saves.

be broken. These can keep sealing and reliable

Flowing of valve is very good, fluid resistance is small, and the flow is large.

When valve plate begins flowing, the back of valve plate has the surfaces
limited what are mutual contradiction to balance the strength in order
to avoid the strength being Torque.

Life is long.

Leakage consumption of the valveseat is low.

Valve plate is easy to take apart.
