Overview

Product Introduction: The piston type chemical special diaphragm valve is a newly developed chemical special diaphragm valve by our company that can be comparable to similar advanced products internationally. The characteristics of this series of products are: 1. No stuffing box, the throttling element is an elastic diaphragm, which can achieve no internal or external leakage when closed, suitable for situations where pollution is not allowed and dangerous restricted areas are not allowed. 2. Smooth flow path, low flow resistance, and high flow capacity, suitable for high concentration and fiber medium suspensions.

1Characteristics and Applications

The piston type chemical special diaphragm valve is a newly developed chemical special diaphragm valve by our company that can be comparable to similar advanced products internationally. The characteristics of this series of products are

1There is no stuffing box, and the throttling element is an elastic diaphragm, which can achieve no internal or external leakage when closed. It is suitable for situations where pollution is not allowed and in dangerous restricted areas.

2Smooth flow path, low flow resistance, and high flow capacity, suitable for high concentration and fiber medium suspensions.

3The aluminum alloy die-casting shell and piston shaped design structure make its appearance more exquisite, with small volume, light weight, and high output force..

4Fluorinated plasticsPVDFThe valve body and PTFE diaphragm make it more corrosion-resistant and have a longer working life, suitable for acidic, alkaline, and corrosive media.

5Compliant with JapanJISStandard, fully interchangeable with imported products. Based on the above characteristics, this product is widely used in industrial sectors such as petroleum, chemical, power station, medicine, health, biotechnology, light industry, and food.

The closing and opening of the diaphragm valve is achieved by the pressure from the pipeline acting on the reinforced rubber diaphragm. When the pressure medium enters the valve control chamber, the diaphragm is pressed down and the valve channel is closed. When the pressure in the control chamber is discharged to the atmosphere or downstream pipeline, the diaphragm rises and the valve channel is opened. Valves do not have valve stems, gaskets, directional seats, etc. The only component that moves in the channel is the diaphragm, so there is no rusting or locking phenomenon, and it has higher stability. Multiple structural and control forms, suitable for various fluid control needs.
