Product Description
Fully welded ball valve is widely used in various fields. Its superior quality and high performance stability cannot be achieved by ordinary cast steel ball valves, and its service life is much longer than cast steel ball valves. Fully welded ball valve is widely used in various pipeline equipment, such as city gas, city heating system, oil refining, shipbuilding, steel, regulating stations and power plants. The fully welded ball valve can work reliably for a long time and requires less maintenance. The installation of the valve is simple, and the installation of the valve is more convenient.
Usage
- City gas: gas outlet lines, main lines and various supply lines.
- Centralized heating: large heating equipment outlet lines, main lines and branch lines.
- Heat exchanger: pipelines and various switching arrangements.
- Metallurgical plant: various liquid transfer lines, exhaust gas outlet lines, gas and heat supply lines, fuel supply lines.
- Various industrial equipment: various heat treatment pipelines, various industrial gas and heat pipelines.
Features and benefits:
1.Floating ball design.
2.The integral pipe of body is welded by cold-pressing for avoid any leakage.
3.Spring loaded seat could well adapt the change of pressure and temperature,ensure precisely contacting between seat and ball.It makes valves with flexible operation on the basis of good sealing.
4.Ball and stem by precisely machning would reduces the friction coefficient,that ensures good sealing and low torque.
5.Leakage rate “A”, small loading to piping and long service life.
Application
- City gas: gas outlet lines, main lines and supply lines.
- Centralized heating: large heating equipment outlet lines, main lines and branch lines.
- Heat exchanger: piping and
