Overview

High temperature resistant butterfly valve, high temperature smoke valve, RTO high temperature butterfly valve, pneumatic high temperature smoke valve, ultra-high temperature flue gas butterfly valve are used in conjunction with manual worm gear, worm gear or pneumatic/electric actuators, and are equipped with radiators to protect the electric/pneumatic actuators and prolong valve operation

Product Details

1. High temperature does not cause jamming

During use, the impact of thermal expansion and contraction of the valve can lead to
The valve stem and packing are stuck, and the valve plate and seat are jammed.
Or excessive margin may lead to excessive leakage rates of the medium both externally and internally.
Before processing, suitable materials will be selected based on temperature, and the expansion amount will be calculated according to the material and thickness. The valve will not lock or jam while ensuring a low leakage rate.

2. The castable does not collapse

Most markets use loose fiber cotton with adhesive or fiber modules stacked in the cut cavity. This will cause the material to become loose and have insufficient density, making it easy for the valve to collapse after a period of operation.
Using high-temperature castables or ceramic fiber shaped parts, it has the characteristics of light weight, high density, high temperature resistance, and no deformation.

3 non necrotic

During use, high temperature is transmitted through the valve stem through heat conduction to reach
At the top of the valve stem, damage to the actuator circuit or sealing ring can cause valve necrosis.
Add fault treatment at the valve stem connection of high-temperature valves to reduce heat; And extend the valve stem and add heat sinks to reduce damage to the valve caused by high temperatures.
