stainless steel tube fitting

Double stop discharge type stainless steel needle valve including body import, main stop valve, stainless steel needle valve, the main body set up have body imports, import from the built-in pipe body connected interface.
Built-in pipe set has three interfaces, and the other two stainless steel hydraulic fitting interfaces respectively with stainless steel needle valve, cut-off valve at a connection; Stainless steel needle valve at the other end connected to the main drains, time stop valve at the other end connected to time drains; Product main stop valve set with flange self-locking device. Beneficial effects of this product: simple structure, low production cost; Valve control function diversification; With self-locking device, to ensure the safety valve.
Type stainless steel needle valve, including body, located in the body of the valve core, as well as the product of the upper part of the connection of valve stem, valve core products including the hemisphere valve core and is located at the upper hemisphere of the handle of the product. This product by changing the valve core structure, stability of the rotation direction of the ball, so as to stabilize the valve sealing performance and greatly improve the sealing effect and prolong the service life of the valve.
Working principle of type stainless steel needle valve is introduced
As you all know, the effect of any valve for stainless steel tube fitting cutting fluid. Depending on the valve core, can be divided into cut-off valve, gate valve, plug valve, ball valve, butterfly valve, stainless steel needle valve type and so on.
Stainless steel needle valve type than any other type of valve that can tolerate more pressure, sealed performance is good, so generally used for small flow, high pressure gas or liquid medium sealing. Type stainless steel needle valve and pressure gauge is used the most appropriate.
The general type stainless steel needle valve type screw thread connection. Nominal pressure: PN2.5 PN4 PN6.4 PN16 PN32MPA: nominal diameter DN5 ~ DN25 applicable medium: oil, water, gas and other non corrosive or corrosive medium applicable temperature: - 20 ℃ ~ + 440 ℃ -- 70 ℃ ~ 240 ℃ 540 ℃ 570 ℃ or less or less manufacturing materials such as: 20 #, 1 cr18ni9ti, 304, 316, 316 l, 12 cr1mov, etc.
Needle valve type
