What type of valve is required for stop valves on a high-pressure boiler?

The stop check free flow gate valve is required for stop valves on a high-pressure boiler due to its design and functionality. This type of valve provides reliable shut-off capabilities while also allowing for controlled flow in one direction. It is particularly effective in high-pressure applications because it can withstand the significant internal pressures encountered in boiler systems, and it provides a robust barrier against backflow, ensuring safety and proper operation of the boiler.

The unique feature of the stop check free flow gate valve is that it combines the benefits of both a stop valve and a check valve, enabling the valve to stop the flow when closed and prevent reversal of flow, which is essential in maintaining the operational integrity of high-pressure systems.
