High Temperature Gate Valves

Hanno Valve High Temperature Gate Valves are used as fully open and fully closed opening and closing devices. The opening and closing components of high-temperature gate valves are gate plates, and the movement direction of the gate plates is perpendicular to the fluid direction. Gate valves can only be fully opened and fully closed, and cannot be adjusted or throttled.

Characteristic Introduction

Lightweight: The body is made of high-grade ductile iron, which reduces the weight by about 20% to 30% compared to traditional gate valves, and is easy to install and maintain.

Flat bottomed gate seat: Traditional gate valves often accumulate in the groove at the bottom of the valve due to external objects such as stones, wooden blocks, cement, iron filings, and debris after flushing the pipe, which can easily cause leakage due to inability to close tightly. The bottom of the elastic seat sealed gate valve adopts the same flat bottomed design as the water pipe machine, which is not easy to cause debris accumulation and allows fluid to flow smoothly.

Overall rubber coating: The gate adopts high-quality rubber for the overall internal and external rubber coating.

Precision cast valve body: The valve body is made of precision casting, and the precise geometric dimensions ensure the sealing of the valve without any precision machining inside the valve body.
