Pneumatic Diaphragm Valve

15/05/2023

Pneumatic diaphragm valve is a new type of electric valve that uses compressed air as the power source and converts the pneumatic signal into an electrical signal through an actuator to drive the valve action. It has the advantages of simple structure, small volume, light weight, etc. It use in the automatic control system of petroleum, chemical, metallurgical and other industries as a regulating and intercepting device.

Diaphragm Valve

15/05/202310/05/2023

Diaphragm valves are a unique type of shut-off valve that control the flow of fluids in pipelines by using the movement of the diaphragm on the valve stem to regulate the opening and closing of the valve. The tightness of these valves is highly prominent, and their applications are wide-ranging due to the variety of diaphragm materials that can be used. Let’s take a closer look at the different types of diaphragm valves and their functions.

Extraction Check Valve

25/04/202324/04/2023

Extraction check valves play an important role in preventing backflow and protecting valuable equipment from damage in steam and water lines. These valves are specifically designed for use in extraction lines from steam turbines to feedwater heaters, heating systems, or process equipment. The extraction check valve is engineered for exceptional reliability and can be configured to remain open until closed by a cylinder actuator on signal.

PTFE PFA Lined Ball Valve

25/04/202318/04/2023

PTFE/PFA lined ball valves are corrosion resistant and anti-corrosion valves specially designed for various pipelines containing corrosive media. According to the working conditions of different valves can choose different lining materials. Such as PTFE, PFA and other corrosion-resistant, aging-resistant materials.

Types of One-way Valves

20/02/202417/04/2023

One-way valves also called check valves or non-return valves. It is a valve where the fluid can only flow along the inlet and the medium at the outlet cannot flow back.

It use in hydraulic systems to prevent the reverse flow of oil, or in pneumatic systems to prevent the reverse flow of compressed air. They play a crucial role in various industries by ensuring the unidirectional flow of substances in pipelines, systems, and equipment, thereby enhancing safety, efficiency, and performance.
