Frequently Asked Questions

What are the Three Main Types of Valves?

The three main types of valves are gate valves, globe valves, and ball valves. Gate valves are used for on/off control of flow, providing minimal resistance when fully opened, while globe valves are designed for throttling and regulating flow, offering greater resistance. Ball valves are known for their quick operation and tight sealing capabilities, making them ideal for applications requiring reliable shut-off.

What is the Purpose of Valves?

What is ATEX valves?

ATEX valves are specialized valves designed to operate safely in potentially explosive atmospheres, adhering to the European Union's ATEX directive. These valves are constructed with materials and designs that prevent ignition sources, ensuring safe operation in industries like oil and gas, chemicals, and mining. By meeting ATEX standards, these valves help mitigate the risk of explosions and enhance safety in hazardous environments.
