This series of products are reliable sealing performance, maintenance-free for 20 years, switch torque light,can be installed in heat transfer stations, district heating pipe network, branch pipes, heat exchanger unit, heat transfer equipment or ancillary equipment connected to other.use for cut off . The main use of the urban heat, city gas, city water supply and drainage lines

 Five Advantages:

1. integral seamless steel tube pressed full-auto welded without leaking outward.

2. PTFE+25% carbon fiber and disc spring feely compensating structure zero leakage.

3. can be directly buried without need of a high ground well,saving the engineering cost.

4. both valve and pipeling are made of the same material, without the condition of uneven sterss.

5. in multiple connection combination, for use with special working conditions.

Zero leakage free maintenance for 20 year

Can be directly buried saving installation costs

Welding stress free 

Multiple combination

Can protect the medium

The valve body and the pipe material are the same and the welding stress will not appear uneven.Pipeline aging resistance and will not be due to the vehicle through the ground infer to geological factors and other factors of deformation

Stem multi-level sealing structure design and can be directly installed .To solve the cost of the construction of the customer room. Also can short the construction period and eliminating the installation costs for customers。

 According to the requirements of customers let the length of the valve stem size personalized design. 

Meet the installation requirements of the pipeline design。

Operators do not need to enter the well in the well with T handle can operate the valve .Operators will not be dangerous due to suffocation.

Technical features of the ball :
1.The machining process is tracked by the computer, and the precision of the three coordinate measurement of shape and position tolerance 
2.The ball is heat treated to eliminate the residual stress in the ball, and the ball can be used for a long time without deformation.

Sealing seat: PTFE carbon fiber5%+5%Mos2  

Features: high temperature resistance, corrosion resistance, abrasion resistance, cold resistance

Du Bush,

Accessories advantage:

1.Adopt international advanced processing technology .A mixture of polytetrafluoroethylene and lead on a surface sintered bronze layer
2.Wear resistance, self lubrication, low friction coefficient to ensure that the stem coaxial. So that the valve opening and closing more easily
