Direct Acting Bellows Pressure Reducing Valve Structural characteristic and purpose.
Pressure Rating: 1.6- 2.5Mpa
Specification: DN15-25
Material: CF8
Standard screwed: NPT BSP
Goole Y14H/F Direct Acting Bellows Pressure Reducing Valve is newly improved product based on MIYAWAKI. This Direct Acting Bellows Pressure Reducing Valve material is Stainless steel, which can be used for some corrosive medium, it can also be used for Air, Steam, etc. The Bellows inside also ensured the high sealing performance of the valve.
This reducing valve is direct acting bellows reducing valve, mainly composed of valve seat, valve flap (steel ball), corrugated tube combined component and spring. Set the outlet pressure through adjusting spring, the opening of valve flap enlarged when the outlet pressure reduced, the opening of valve flap decreased when the outlet pressure reached to the set pressure. The valve pressure of the medium acts on the area of corrugated tube and transduce to adjusting spring, realizing the function of pressure reducing and regulating. This reducing valve is designed in meet of the need of energy saving. It has the characteristics of multi-function and light. It is widely applied on water, steam, air, oxygen, liquefied gas pipe of factory and hotel. You can adjust the pressure by rotating the plastic hand wheel, no need to use tool, the connection and installation is very convenient. The internal structure use corrugated tube, the sealing face has filtering mesh protecting device, which protect the internal parts from damage, and greatly prolong the service life.
