Product description

All welded ball valves

Features:

1. The body is composed of steel pipe welding.

2. Ball mat adopts reinforced PTFE.

3. The valve rod adopts anti-explosion design.

4. The temperature range: -60-200 ℃

5. Drive mode: manual or turbine drive.

6. Inspection standard: Api 598

 

Purpose:

City gas: gas output pipeline, trunk line and sub-line supply pipeline, etc.

Central heating: large heating equipment output pipeline, trunk line and sub-line.

Heat exchanger: piping and the opening and closing of each circuit.

Steel mills: all kinds of fluid pipes, exhaust pipes, gas and heat supply pipes, fuel supply pipes.

All kinds of industrial heat treatment equipment: all kinds of pipes, all kinds of industrial gas and heat pipe.

Features:

All welded ball valve, and no phenomenon such as external leakage.

Features:

Because the seat consists of the carbonization Teflon seal ring and disc springs, so it’s adaptable to changes in pressure and temperature, and will not produce any release and slid within pressure and temperature range.

Sphere machining process has advanced computer detector tracking detection, so the sphere machining precision is high.

Due to the valve body material equal wit pipe material, it won't appear uneven stress, also won't occur deformation because of the earthquake and the vehicle through the ground. Pipe has ageing resistance.

 Sealing ring ontology adopts RPTFE material with content of 25% Carbon, to guarantee completely no leakage (0%).

 Direct buried type welding ball valve can be directly buried in the ground, don't have to build high large valve well, only need to set up small shallow Wells on the ground. It greatly saves construction cost and project time.

According to the pipeline's construction and the design requirements, adjust the body length and the valve stem height.

Sphere machining accuracy is very precision, convenient operation, no harmful interference.

Adopt advanced raw materials, can keep pressure more than PN25.

Compared with the same specification products in the same industry, the body is small, but beautiful.

In case of normal operation and use of the valve, the service life is over 15 years.
