Q71F-16P German standard ultra-thin one-piece clamp ball valve

Product Overview

The Q71F-16C/P/R German standard ultra-thin one-piece clamp ball valve adopts an integral cast valve body, combined with a valve cover and ball core assembly, with a tight structure, small volume, light weight, and ultra short installation distance. It is an angular stroke valve that uses the stem connecting shaft rotation to achieve opening and closing function. The ball core V-shaped opening can also be designed to achieve flow regulation function. Widely used in various pipeline systems such as petroleum, chemical, pharmaceutical, and food industries.

Unique advantages

• Low torque, elastic valve seat and ball core have controllable sealing pressure and elastic contact, providing elastic avoidance for the ball to rotate. The operating torque is uniform and unobstructed, with a smooth feel and no locking during opening; Cutting the edge of the valve seat to avoid the ball mouth not being embedded in the valve seat under high pressure difference conditions.
• The valve seat has strong sealing performance, and the pre sealing of the elastic valve seat forms a useful self sealing effect under the pressure of the medium when the upstream valve seat is closed.
• The valve seat has a long service life, the pre compression stroke of the elastic valve seat is long, the wear compensation is large, and it has both upstream sealing and downstream support forms, so that during the stroke from the beginning of closure to before sealing, it is sealed without being affected by medium pressure. Only when a seal is formed at the moment of closure, the pressure on the sealing surface of the valve seat rises, thereby achieving sealing durability.
• Valve seat trimming, utilizing the non supporting area between the sphere and the valve seat, and wrapping the valve seat liner ring to prevent cold flow collapse, thereby achieving high pressure bearing.
• The downward protruding valve stem design prevents flying out and also prevents leakage.
• Prevent static electricity devices, ensure that the current between the ball core, valve stem, and valve body is guided outward, and avoid safety accidents caused by static electricity.
• O-ring has good self sealing effect, ensuring the sealing effect on the medium inside the valve chamber.
• V-shaped packing, precision machining and assembly of packing pressure ring plane seal to achieve leak free effect.
• Disc spring gasket, to adapt to automatic elastic compensation in case of wear of sealing packing ring, thereby reducing leakage.
• Full flow design ensures fast flow of medium in the valve, saving time, energy, etc.
• According to user and system needs, clamp type ultra-thin ball valves can also be equipped with automatic control devices such as electric and pneumatic to achieve remote or automatic control.
