In a tightly closed storage things condition, whether or not the tank will be because of the overpressure and concave and become warped flat bottom, the key whether the tank breathing air flow smoothly through the breather valve. Breathing Industrial Valves existing condition there is no way for a third of matter. Is in the process of breathing stem and stem pressure testing points, can meet the requirements of stem is decided on the breather valve can be semi-automatic stem through mind. To sum up, the respiration valve stem requirement is that the pressure in the half a tank of gas pressure is greater than the stem under the premise of guarantee the respiration valve under the background of a variety of assignments and is happy with the tank to breathe the mind. 。 Q: breathing valve stem requirements: a: breathing Industrial Valves basic utility has two: one is tightly closed oil storage tank safety; Second, the loss of oil evaporation damage. Existing breathing valve can fit 1 kind of things, to the second kind of things can also basic suitable condition, but most of the oil depot, to avoid the tank overpressure of hair didn't survive, do manual by-pass disposal. Marine valve from the process of oil storage tank breathing condition: there are three things 1) Due to air temperature graded, gas tank size change, small flow rate of oil tank breathing; ( 2) When performing when sending and receiving oil, along with the temperature of the gas tank body degree changes caused by large tank flow breathing; ( 3) Climate change and other things cause a large tank flow breathing condition. The latter requires the respiration valve have satisfactory tightly closed, the former is the requirement of breathing valve matter most. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.

Anyone who has seen the latest y gate valve wedge valve in operation cannot help but be impressed with how far the technology has progressed over the past few years.
Serving others for customers a better life with double flanged gate valve for employees respect and opportunity.
resilient seated valve problems are nothing new, almost every one of us have to go through them at some point of our lives and some of us never get rid of them. with the development of os&y valve technology, now provides a perfect cure for that.
We are professional in manufacturing gate valve, and always emphasize the technology and quality during the producing procedure.
The global market is estimated to reach a value of almost resilient gate valve in the next decade. have a robust position in the resilient seal gate valve market because of its proven high potency in os gate valve.
