Cast Steel Flange Butterfly Valve D343H-16C

Features

1. The unique three-way eccentric design enables friction-free transmission between sealing surfaces, extending the service life of the valve.

2. An elastic seal is created by torque.

3. The clever wedge-shaped design enables the valve to have an automatic sealing function that becomes tighter and tighter as it is closed, and the sealing surfaces are compensatory and have zero leakage.

4. Small size, lightweight, easy to operate, and easy to install.

5. Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.

6. The material of the replacement parts can be suitable for various media, and the lining can be anti-corrosion (lining F46. GXPP. PO, etc.).

7. Diversified continuous structures: clamping, flange, butt welding.

Product Overview

The butterfly valve has a simple structure, small in size and lightweight, and is composed of only a few parts. Moreover, it only needs to be rotated 90* to open and close quickly, which is simple to operate. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure drop generated by the valve is very small, so it has good flow control characteristics. Butterfly valves have two sealing types: elastic seal and metal seal. For elastic sealing valves, the sealing ring can be embedded in the valve body or attached to the periphery of the butterfly plate.

Product Use

Used in gas pipelines in the sulfuric acid industry: furnace blower entrances and exits, relay fan entrances and exits, electric defogger series and connecting valves, S02 main blower entrances and exits, converter adjustment, preheater entrances and exits, etc. to adjust and cut off the gas volume.

Used for burning sulfur in the sulfur acid production system. In the conversion and dry suction section, it is the preferred brand of valves for sulfur acid production equipment. It is considered by the majority of users to have good sealing performance, light operation, corrosion resistance, high-temperature resistance, easy operation, flexibility, and safe and reliable use of butterfly valves, and has received a large number of butterfly valves. Promote use.

Also widely used in chemical, petrochemical, smelting, pharmaceutical, food, and other industries SO2. Steam, air, gas, ammonia, CO2 gas, oil, water. Saltwater, alkali, seawater, nitric acid, hydrochloric acid, sulfuric acid, and phosphoric acid It is used as regulating and intercepting devices on pipelines with equal media.
