The pressure gauge three-way plug valve installed on the boiler must use a pressure gauge three-way plug valve to connect the drum, steam, and space for flushing the water trap, calibration, and cutting and replacing the pressure gauge.

Structure and characteristics of three-way plug valve for pressure gauge:

The material of the valve body for the three-way plug valve of the pressure gauge is forged from steel parts, and the valve stem is made of stainless steel column type valve stem. The sealing liner is made of special graphite material, which can flexibly change the direction of the switch during use without thermal expansion or biting. The sealing performance is reliable, and the replacement and maintenance of accessories are convenient.

Structure and characteristics of three-way plug valve for pressure gauge

Pressure gauge three-way plug valve connection method:

1. The gauge head is prepared according to the standard pressure gauge M20 × 1.5

2. There are two types of steam inlets, M20 × 1.5 and ZG1/2, each with internal threads.

Needle valve is a type of valve that can be adjusted and has a wide range of applications, such as the cutting distance used for flame cutting, and the knob for adjusting flame temperature is the needle valve. Instrument needle valve is an important component of the instrument measurement pipeline system, mainly including globe valve and ball valve. Its function is to open or cut off pipeline paths. The valve core of a needle valve is a very pointed cone, inserted into the valve seat like a needle, hence the name.
