The напълно заварен сферичен кран за високо налягане series are fully welded forged valves that are particularly suitable for the gas transportation and storage industry.
We have designed our fully welded ball valves to be separate from the bolts that traditionally connect the body to avoid potential leakage in hazardous connections.
В допълнение, the valves are made of forged steel. The same particle size and uniform thickness prevent shrinkage and other inherent imperfections in the valve. The biggest advantage of all welded ball valves is zero leakage.

Draining: When the valve cavity is drained in operation, the valve medium is also drained at the same time, and the pressure value is tested directly through the drain hole.
Why choose Farpro high pressure fully welded ball valve?
Seat and Sealing
The high pressure ball valve is constructed with a base seal and incorporates a metal base ring soft seal material (embedded PTFE). We designed it in a modular barb configuration to ensure the effectiveness of the valve opening and closing during the process of being closed.
To ensure a perfect seal, a spring-preloaded sealing seat is used as the initial sealing pressure to ensure effective closure at the downstream end of the pipe. От друга страна, the media particles are injected with the help of zero-sealing action, using the Teflon metal seal as the primary seal and the metal-to-metal seal as the secondary seal. Such a structure is capable of responding to various emergencies.
with the Ball Bearing Shaft
The ball bearing adopts two upper and lower plate type structure, when the valve opens and closes such a stem rotation structure can only dilute the torsional force rather than bending stress and small torque. This structure greatly extends the service life of the valve.
Welded ball valve DBB design features
In accordance with DBB standards, the product is designed to obtain a double barrier and leakage as well as a cavity in the automatic pressure relief structure.
In the discharge valve cavity, the upstream/downstream base will be automatically shut off at the same time to ensure the safety of drainage.
Versatile Operation Design of Welded Ball Valve
The valves are designed to be fitted with electric, пневматичен, hydraulic, gas-hydraulic interaction and other devices and ensure automatic operation. Remote pipelines can be used for satellite monitoring systems.
When the pressure drop or duration of the pipeline reaches - a certain range, the remote emergency valve will be closed with an opening and closing time of 0.05 to 1s.
Underground High Pressure Welded Ball Valve
The all-welded body structure of the valve stem can be extended, so the valve can be installed underground.
As the whole structure of the welded main body of the high-pressure underground welded ball valve has cathode tube and outer surface corrosion resistance, it can effectively prevent corrosion and stress corrosion from occurring.
