Q647F-16C Pneumatic Stainless Steel Two Piece Fixed Ball Valve

Product Description

Product Overview

The Q647F-16C Pneumatic Stainless Steel Two Piece Fixed Ball Valve excellent sealing performance, large flow coefficient, small flow resistance coefficient, simple structure, long service life; The pneumatic actuator has a corrosion-resistant casing, visible position pointer display, lightweight design, and maintenance free. The mechanical friction of the actuator is between Ra0.4 and 0.6, ensuring that the friction is reduced to the minimum value and guaranteeing the longevity of the actuator. The smooth components ensure a low friction rate to avoid metal to metal friction and prolong the working life of the actuator. Each actuator undergoes 100% rotation and sealing testing before leaving the factory, with a service life of over 1 million cycles.
Adopting dewaxing precision casting, fireproof structure design, and unique high platform design for easy installation of actuators; There is an anti-static device between the valve stem and the valve body, an explosion-proof device on the valve stem, and a pressure balance hole on the steel ball; Double layer valve stem packing and two disc shaped spring plate devices, valve stem leakage meets the testing requirements of German TUV TA-LUFT, and the valve body has a device for cleaning the valve chamber.

Unique Advantages

Low fluid resistance. Ball valves have the lowest fluid resistance among all valve types, even for reduced diameter ball valves, their fluid resistance is quite small.
The thrust bearing reduces the friction torque of the valve stem, allowing for long-term balanced and flexible operation of the valve stem.
The valve seat has good sealing performance and is made of sealing rings made of materials such as polytetrafluoroethylene. The structure is easy to seal, and the sealing ability of the ball valve increases with the increase of medium pressure.
The valve stem seal is reliable. As the valve stem only rotates and does not move up or down, the packing seal of the valve stem is not easily damaged, and the sealing ability increases with the increase of medium pressure.
Due to the good self-lubricating properties of materials such as polytetrafluoroethylene, the friction loss with the ball is small, and the service life of the ball valve is long.
The bottom mounted valve stem and the protruding step at the head of the valve stem prevent the valve stem from spraying out. In the event of a fire causing damage to the valve stem seal, the protruding step can also form a metal contact with the valve body to ensure the valve stem seal.
