Stainless Steel Flange End Foot Check Valve
Foot Valve

Brief Introduction
Foot valve is a kind of energy-saving valve, usually installed at the bottom of pump suction pipe, to prevent medium in the pipe flow back to water source. There are many inlet holes and reinforcing ribs in the valve cover, so the pipe will not be easily clogged up.

Features:

DN : DN15~DN400
PN:2.5~25bar
Material:cast iron,Cast Steel,Stainless Steel



Working Principle

Foot valve consists of cover, disc, bush, seal ring, etc.  Water enter into the valve body through cover. Under the influence of flow pressure, disc will be opened. When stop, pressure in the oulet pipe will close the disc instantly, water will not flow back to water source. It effects the functions of smooth pumping and saves water loss.

Tube Type Heat Exchanger

fixed tube heat exchanger
The structure of fixed tubesheet heat exchanger is simple, compact and cheap, but cannot be cleaned mechanically. This tube bundle of heat exchanger is connected ontubeplate, which is welded on both ends of the shell, the top cover connected are equipped with fluid inlet and outlet nozzles.A series of baffles perpendicular to the tube bundle are usually installed outside.Two different temperatures fluids inside out, therefor regid material is used. Therefore, to avoid thermal expansion between tubes inside out when temperature difference is higher than 50°C, automatic temperature compensator needs to be installed.However, the compensation device can only be used in the case that the pressure of the shell side fluid is not high when the temperature difference between the shell wall and the pipe wall is less than 60-70°C. Generally, when shell side pressure exceeds 0.6Mpa, because compensation ring is too thick, it is difficult to expand and lose the role of temperature compensation, other structures should be considered.
