The materials are carefully selected for durability. Easy to open and close, no need for a manhole cover. Pipeline connections should remain natural and smooth, avoiding bending forces perpendicular to the pipeline. The gate valve, valve chamber, and well pipe sections should be installed vertically. During installation, ensure that the expansion pipe and expansion rod can better avoid inconveniences caused by missing manhole covers. The extension rod of the soft-seal gate valve can be custom-made flexibly according to the distance from the burial point to the ground, ensuring the most suitable length. The top of the Puhui brand extension rod soft-seal gate valve is equipped with

1. Fully Encapsulated Rubber: The gate adopts full encapsulation with rubber, providing excellent coverage performance and precise geometric dimensions, ensuring reliable sealing and long service life.

2. Lightweight: The valve body is made of ductile iron, making it lightweight and easy to install.

3. Flat-Bottom Valve Seat: The bottom adopts a flat-bottom valve seat design similar to that of water pipes, preventing debris accumulation and ensuring more reliable sealing.

4. Corrosion Resistance: The inner cavity is coated with non-toxic epoxy resin to prevent corrosion and rust, making it suitable not only for drinking water but also for sewage systems.
