Nonstandard valves, valve parts and other casting and forging products as clients drawing.
Technical Parameter for fully welded ball valve:
Nominal Diameter: DN20~DN1400
Nominal Pressure: 1.6-4.0MPa
Applicable temperature: -40~200ºC
Connection Type: Butt welded/Flanged/Threaded/ Threaded flange
Operation: Manual/with gear/electrical/worm gear/pneumatic/hydraulic
Standard: GB/T12237-2007,API6D,ASME B16.34,ISO 9001,KC,TS.
Fully welded ball valve 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. Directly buried without need of a high ground well, saving the engineering cost.
4. Both valve and pipeline are made of the same material, without the condition of uneven stress.
5. Multiple connection combination, fire and electrical prevention design, using in the special
Working conditions.
6. Maintenance-free for 20 years.

Under the basic model, we have extended non-standard telescopic machines such as hydraulic telescopic machine, hump telescopic machine, height-increasing frame extension machine, platform extension machine with standing people, and movable extension machine with wheels on raised frame to meet the different needs of customers. .
Hydraulic telescopic machine is suitable for loading and unloading of carts to improve efficiency.
The hump telescopic machine is suitable for docking high line bodies. Generally, the matrix line body needs to be docked with the telescopic machine, which can be used with hydraulic pressure.
The height-increasing telescopic machine is suitable for the insufficient height of the site, and is used to increase the height to meet the docking of express vehicles.
The telescopic machine with station platform is also an improved version that also improves express loading and unloading.
Elevated Shelf with Wheels Movable Telescoping Machine is suitable for limited space on site, can be moved and can be placed out of the way when not in use
