1.Pipe Valve Joint Introduction
The valve in the pipe fittings is a mainly component.
The production of valves would adopt different mechanical manufacturing methods according to the pressure and working environment. (Such as casting, forging, etc.)
Valve bodies used in medium- and low-pressure environments are usually produced by casting methods (precision casting, gravity casting, low pressure casting).
The valve core and valve seat sealing ring can effectively withstand the pressure from water, gas, or oil after forming a seal.
In addition, the selected materials of the valve body are based on different process specification. Materials are cast iron, cast steel, stainless steel, carbon steel, etc. on common.

3.Product Feature And Application
METALLECA® Pipe Valve Joints, one of Pipe fittings component, are used to transfer liquid, gas or fluid solid, and have supporting and reinforcing structures.
When transferring fluid solids, it is usually applied water or gas as the medium.
The pipeline must be spill-proof and bearing temperature, pressure (internal pressure), and corrosion & abrasion resistance.
For example, crude oil and heavy oil pipelines must be able to withstand a temperature of about 100°C; steam pipelines must withstand a temperature of about 150°C.
On the other hand, the internal pressure of the water supply pipeline is about 0.5 to 1.0 MPa; the compressed air and steam pipeline is about 0.8 to 1.3 MPa.
The pipeline structure should also bear its own weight, the weight of the conveyed materials and various external loads. (Such as soil, water, wind, vibration, thermal expansion and contraction, and the load generated by people, vehicles, construction machinery, etc.)
