High performance riser ball valve

Nominal pressure:PN0.4~1.6MPa
Nominal diameter:DN25~100mm

High performance riser ball valve is the latest product developed on the basis of the introduction of Germany through the wall entry pipe safety fire ball valve technology. It is mainly used for cutting off the medium in emergency or normal maintenance.


Reliable seal construction

The ball and PTFE seat form a primary seal under the action of a disc spring, and the back of the seat is provided with an O-ring to help seal. Once the PTFE seat is burned, the ball forms a metal seal with the body under the force of the spring.


Operating structure for anti-theft

The special shape opening and closing mechanism is hidden in the upper part of the valve body, and the special wrench can be operated; The top protective cover prevents rain and other debris, to achieve the purpose of special management and safe gas use.


Low operation twist

A specially designed slotted disc spring with a radial ring provides the valve seal force, resulting in extremely low opening and closing torque compared to conventional ball valves.


Valve stem structure

The inverted valve is blown out by the pressure in the cavity to avoid safety hazards; Two self-tightening O-rings ensure stem seal.


Antistatic structure

After the disc spring compression, the ball and the valve body form a conduction road, the valve in the process of opening and closing the static electricity generated.


External anticorrosion

Cathodic electrophoretic coating is used to prevent the valve from oxidizing and rusting effectively and prolong its life.
