Frequently Asked Questions
What is an angle air valve used for?
Angle air valves automatically release trapped air from pressurized pipelines and allow air to enter when negative pressure occurs, protecting the system from vacuum collapse and air binding.
What materials are used in this valve?
The body and cover are forged steel for excellent strength, while the internal trim is stainless steel to prevent corrosion and ensure reliable sealing in aggressive marine fluids.
What pipe sizes are available?
This valve is offered in DN15, DN20, DN25, DN32, DN40, and DN50 sizes (1/2" to 2") with BSP threaded connections for standard marine piping.
Can this valve be used in seawater systems?
Yes, the forged steel body with stainless steel internals is suitable for seawater, freshwater, and oil-laden media as commonly encountered in shipboard systems.
