Air Valve single chamber:
1.
Application: water transition pipes
2.
Function:
a. when the pipe is
being filled with water, the air valve automatically let air out of the empty
pipes. The air must be released rapidly
to make sure that the pressure does not increase in that area as flow is restricted
by the air in the pipe.
b. when the pipe is being
empty, the air valve must let air into the pipes rapidly to prevent the
pressure from dropping and forming a vacuum in the pipe.
3.
Surface coating:
Internally and externally coated with
fusion bonding epoxy coating of minimum thickness of 250um. As required,
Certification corresponding to drinking water like KTW, WRAS could be
available.
4．Quality traceability
All the valves are with serial no. which
could ensure the traceability of the production and quality control.

Centrifugal chemical pump is the chemical industry's most widely used products, there are several types of centrifugal chemical pump according to the material is divided into polypropylene, fluorine plastic, stainless steel several, according to the pump body structure is divided into direct connection, coupling, legislation Type, horizontal several, according to actual needs can refer to choose the right product.
　　
Centrifugal chemical pump precautions:
　　
(1) The installation of chemical centrifugal pump pipe weight can not be added to the pump. Should have their own support, so as not to affect the operation of deformation and life expectancy.
　　
(2) stainless steel chemical pipeline pump and the motor is the overall structure, no need to find the correct installation, so the installation is very convenient.
　　
(3) It is necessary to tighten the anchor bolts during installation to avoid the influence of vibration on the performance of centrifugal chemical pumps during start-up.
　　
(4) before installing centrifugal chemical pump should carefully check the pump flow channel has no effect on the operation of the pump hard material (such as stones, iron tablets, etc.), so as to avoid centrifugal pump damage to run impeller and pump body.
　　
(5) For maintenance convenience and safety, install a regulating valve in the inlet and outlet pipes of the centrifugal chemical pump and a pressure gauge near the pump outlet to ensure the operation within the rated head and flow range to ensure the normal operation of the pump , Increase the life of chemical pump.
　　
(6) The pump should be installed at the end of the suction valve, unless the valve is self-priming pump can not be installed, and the inlet pipe should not have too many corners, while not leaking, leakage phenomenon.
　　
(7) Discharge line such as Check Valve should be installed outside the Gate Valve.
　　
(8) Turn the pump shaft after installation, the impeller should have the friction noise or stuck phenomenon, otherwise the pump should be disassembled to check the reason.
　　
(9) Centrifugal chemical pump installation is divided into rigid connection and flexible connection installation.
