2. Product Overview
"Boang Brand" standard gas ball valve is an indispensable control component in the polyethylene gas pipe network system. The working pressure of the polyethylene ball valve can match that of polyethylene pipes. Its opening and closing torque is small, the valve is corrosion-free, does not require maintenance and repair, and has a service life of 10 years. The integrity of the polyethylene pipe network system is improved. The integral valve body eliminates the possibility of leakage. When the ball valve is connected to the pipeline, there is no need to set up a valve well and direct burial construction. The straight ports at both ends of the valve body can be connected by butt welding or electrofusion welding for convenient opening and closing of the valve. Operate on the ground.

4. Product performance
For the sealing structure of the valve, consider the characteristics of plastics, design a reasonable upper and lower support structure of the valve core, appropriate sealing materials, between the stem and the valve body More than one rubber ring is used between them, so the sealing performance is excellent
. The molding process of the valve core and valve body meets the requirements of the valve structure, strength and stiffness
. Strengthening the sealing of the ball (rubber) , widen the contact surface between the ball and the seal, and make it full of elasticity during design, so the oversized sealing surface design is enough to ensure the sealing performance requirements
, forming mold manufacturing and debugging
, design the ball aperture to the full diameter, minimizing pressure loss
. Designed to be buried underground, minimizing the distance for dissipation. Small valve wells can be used
. Due to the characteristics of polyethylene, it has corrosion resistance, flexibility, and chemical resistance. ﹑Poor cold resistance
The bottom of the valve body is designed to be flat, making it easy to install it flat during construction.
