What is 4 inch gate valve brass

4 inch gate valve brass have small flow resistance.

The medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small.

4 inch gate valve brass has less effort when opening and closing. It is compared with the brass ball valves, because whether it is open or closed, the direction of movement of the gate is perpendicular to the direction of medium flow.

Applications of 4 inch gate valve brass

4 inch gate valve brass is applicable medium: water, oil, gas, steam, etc. Application areas: mechanical equipment, chemical equipment, general parts, industrial equipment, water supply and drainage equipment, paper-making equipment, pharmaceutical equipment, general equipment, petrochemical equipment, power equipment, metallurgical powder equipment, mining equipment, municipal, electronic industry, etc.

How to select 4 inch gate valve brass

There are three different types of 4 inch gate valve brass: full bore, standard bore, reduced bore, the bigger bore size, the better flow rate, standard bore PN16 brass gate valves are more used. Thread types differ from markets and applications: BSP threads for Europe and NPT threads for North America, also other metric threads, which you must confirm before buying brass gate valves.

Chemical compositions for 4 inch gate valve brass

CW614N and CW617N brass materials are widely used for European long-stem brass gate valves.

CW617N brass long-stem brass gate valves have better physical property to stand higher working pressure and temperature, more importantly the Pb percentage share is less than 2.5% and applicable for drinking water systems, good for environment and people's health.

CW614N long-stem brass gate valve is also popularly used because of similar compositions and lower costs, suitable for those applications without much environmental requirements.
