Frequently Asked Questions
What is the maximum working pressure of this valve?
This bronze screw down check globe valve is rated for 16 kgf/cm², which equals approximately 1.6 MPa or 230 psi.
Which fluids can be used with this valve?
The valve is suitable for seawater, fresh water, fuel oil, and other marine compatible fluids. Always verify material compatibility with your specific medium before installation.
What does 'union bonnet' mean?
Union bonnet construction uses a threaded union nut to hold the bonnet to the body. This allows the valve to be opened or serviced without unthreading the entire valve from the pipeline.
Is this valve a combination of a globe valve and check valve?
Yes, it functions as a screw-down globe valve for positive shut-off and also prevents reverse flow. The check action helps protect pumps and equipment from back pressure and backflow damage.
