Manual Check Valve is a highly durable one way flow unit which is especially designed to prevent the reverse flow of the fluid in industrial systems to prevent damages due to phenomenon such as water hammering which gives extra life to the pipe lines and the installations fixed within the fluid system. This valve is designed and developed by our team of skilled professionals by using premium grade materials which imparts greater strength and robustness that makes it ideal for harsh industrial conditions.
Manual Check Valve Specifications:

3. Material: SS304, SS316, WCB, CI, WC6
4. Color: Steel
Q1: What is a manual check valve?
Ans: A manual check valve is a mechanical device used to control the flow of fluids or gases in a system by allowing them to flow in one direction while preventing backflow in the opposite direction.
Q2: How does a manual check valve work?
Ans: Manual check valves operate using a simple mechanism. A spring-loaded disc or ball inside the valve allows flow in one direction while blocking flow in the opposite direction. When the fluid or gas pressure is greater on the inlet side, the valve opens, and when pressure is greater on the outlet side, the valve closes.
Q3: Where are manual check valves used?
Ans: Manual check valves are used in a variety of applications including water and wastewater systems, plumbing, HVAC systems, industrial processes, oil and gas pipelines, and more.
Q4: What are the benefits of using manual check valves?
Ans: Manual check valves offer reliable backflow prevention, help maintain system efficiency, and prevent damage to equipment by preventing reverse flow. They are relatively simple to install and require minimal maintenance.
Q5: Are manual check valves adjustable?
Ans: Manual check valves are typically not adjustable in terms of pressure settings. They are designed to open and close based on the pressure differential across the valve.
Q6: Can manual check valves be installed in any orientation?
Ans: Check valves often have specific orientations for optimal performance. It's important to follow the manufacturer's guidelines for installation to ensure proper functionality.
Q7: Are manual check valves suitable for all types of fluids and gases?
Ans: Manual check valves are designed for specific fluids and gases. It's important to choose a valve that is compatible with the substance being transported to prevent corrosion, erosion, or malfunction.
Q8: How do I maintain a manual check valve?
Ans: Regular inspection is crucial to maintain manual check valves. Clean them if they become clogged, replace any damaged components, and ensure the valve opens and closes freely. Lubrication might be necessary for some models.
Q9: What is the difference between a swing check valve and a lift check valve?
Ans: A swing check valve has a hinged disc that swings open when the flow goes in the correct direction and closes when there's backflow. A lift check valve has a guided disc that lifts off the seat to allow flow and closes under backflow pressure.
Q10: Can manual check valves handle high pressures and temperatures?
Ans: The pressure and temperature ratings of manual check valves vary depending on their design and materials. Some valves are designed to handle high pressures and temperatures, while others are suited for lower-pressure applications.
