Q61 F/N-160/320 C/P Welded high pressure ball valve

First, Q61N high-pressure butt welding ball valve related overview

Q61N high pressure butt to weld ball valve valve body in the two seats along the vertical section of the valve channel axis is divided into three parts, the whole valve along the central axis of the valve stem symmetry, high pressure forged steel ball valve in the pipeline is mainly used to cut off, distribution and change the direction of media flow. Its large pivot structure ensures the accurate center position of the ball under high pressure, ensuring good operating performance of the valve.

Second, the characteristics of Q61N high-pressure butt welding ball valve

1. When the stagnant pressure in the valve cavity abnormally exceeds the pre-tightening force of the spring, the seat will retreat from the ball to achieve the effect of automatic pressure relief, and the seat will automatically reset after pressure relief.

2. In case of fire or abnormal temperature rise, when the sealing ring of the seat is burned or softened, under the action of spring and medium pressure, the spherical part of the support ring and the ball form metal-to-metal contact, achieving temporary sealing effect, and organizing the fire to further expand.

3, packing gland parts sealed with PTFR packing and O-ring double seal, especially suitable for gas medium, packing in the packing tray, can be used at any time with low friction coefficient of the new SF type self-lubricating sliding bushing, reduce the operating torque.

Scope of application

Urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection.High pressure butt welding ball valve is the material is forged out, the density of the material is much larger than the casting density, especially suitable for the manufacturing of high pressure ball valve, high pressure forged steel ball valve closing parts of the ball around the center line of the valve body for rotation to achieve the opening and closing of a ball valve, the seal is embedded in the stainless steel seat, the metal seat with a spring at the end, when the sealing surface wear or burn, The valve seat is pushed with the ball under the action of a spring to form a metal seal. It has a unique automatic pressure relief function, when the pressure of the medium in the valve cavity exceeds the spring preload force, the outlet end of the valve seat is withdrawn from the ball, to achieve automatic pressure relief effect, and the valve seat automatically returns after pressure relief, suitable for water, solvent, acid and natural gas and other general working media, but also suitable for poor working conditions of the media, such as oxygen, hydrogen peroxide, methane and ethylene, etc. It is widely used in various industries.

Packing of Standard Packing:

 Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 2022 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
