[Produktbeschreibung]

Product Overview:
But off the main valve or connected piping used in the media, can also be used for the regulation of fluids in pipes and control; and can be equipped with a pneumatic actuator, respectively, the electric actuator to form a variety of pneumatic valve or electric cut off the ball, to apply to all users. Valve is mainly applied to natural gas, oil, chemical, metallurgy, urban construction, environmental, pharmaceutical, food and other industries.
PUMASON ball valves to meet the different needs of various customers; product nominal pressure from PN0.1-PN10Mpa, nominal diameter from DN15-DN600; temperatures from -196 ° C ~ +600 ° C. Products can be DIN, ANSI, JIS and other standards of production, pay attention to more than nominal diameter valve DN200, the company recommended a fixed ball valve.
Structural features:
1.Unique seat sealing structure:
PUMASON valve provided with dual slope elastic ring or V-groove design of flexible ring structure, to ensure the reliability of sealing, for low-voltage, low voltage or ultra-vacuum conditions with the ball, using spring loaded seat seal structure, to ensure long-term reliable sealing valve, the high temperature ball valve seat material can be used for the bit of polystyrene or metal materials.
2.body structure:
According to customer needs and the actual working conditions of the different design for casting, forging and welding structure in three forms, all of which the main valve of welded structures for underground use.
3.Reliable stem seal:
Stem seal downloading using inverted structure, inverted sealing the sealing force increased with the increase of the pressure medium, it can ensure a reliable stem sealing, and when the valve cavity abnormalities boost, the valve stem will not spray.
4.Automatic pressure relief structure:
Abnormal increase in the pressure chamber in which the phenomenon, the media can rely on their own in the cavity of the thrust to promote and automatic pressure relief valve seat, thereby ensuring the safety valve.
5.Structural fire protection:
According to conditions and needs of users, ball valve can be designed for structural fire protection. Ball of fire-resistant design standards such as the implementation of API607 and JB/T6899 provisions in the event of a fire burning when leaving a soft seal, valve structure can prevent the fire a large number of media leaks and prevent further expansion of the fire.
6.Anti-static structure:
When operating the valve, due to the friction between the ball and seat, and will produce electrostatic charge accumulation on the sphere, in order to prevent static electricity sparks, especially on the valve setting static devices, will accumulate in the export charge on the sphere.
7.Blocks and excretion:
When the valve is closed, on the downstream side of the valve seat to block fluid, body cavity of the stagnation in the excretion of plant material can be excreted. (For fixed ball valve).
