brass needle valve product overview:

Brass instrument type valve is also called brass needle valve, (brass internal thread the needle valve, brass ferrule needle valve, brass type external thread the needle valve) is an important part of the meter in the piping system, connect with easy installation and disassembly, fastening, conducive to fire, sealed performance is good wait for an advantage, brass type needle valve is a valve can be precisely adjusted, has a wide use, such as oil refining, chemical, pharmaceutical, oil, scientific experiments, electrical engineering equipment and instrument measuring an advanced pipeline connection mode of the valve. Brass sealing good, long service life, even if the sealing surface damage, also need to replace quick-wear part only, can continue to use. Brass instrument type needle valve is the instrument measuring piping system important constituent, its function is to open or cut off the pipeline path. Brass type needle valve valve core is a very sharp cone, like the needle inserted into the seat, hence the name.

Second, the brass pin type valve working principle:

Type of valve is used for cutting fluid. Brass needle valve type shape than other types of valves that can tolerate more pressure, sealed performance is good, so generally used for small flow, high pressure gas or liquid medium sealing. Type needle valve and pressure gauge is used the most appropriate. General type needle valve type thread, card sets of connection. Nominal pressure: PN1.0 PN4 PN6.4 PN10 a nominal size: 1/4 "to 1/2" applicable medium: oil, water, gas and other non corrosive or corrosive medium applicable temperature: - 20 ℃ ~ 200 ℃ or less and other manufacturing material: brass, wrought brass H62, etc

Three, brass type needle valve performance specifications:

1, nominal pressure: 2.5 Mpa PN1.0

2, suitable medium: air or non corrosive or corrosive medium

3, suitable for temperature: room temperature and 200 ℃ or less

4, nominal size: 1/4 "to 1/2"

5, manufacturing material: brass, wrought brass H62, etc

The order need to know:

1, the valve pressure rating. Nominal pressure PN class/Mpa, kg force KGF, CL, imperial PSI

2, the valve specifications.

3, connection mode: thread, socket, butt welding, card sets, etc.

4, the length of the valve structure standards.

5, the valve structure:straight, Angle type.

6, the main valve parts material or fluid performance.
