Anti Water Hammer Function Stainless Steel Pilots Surge Anticipating Valve
Anti Water Hammer Stainless Steel Pilots Surge Anticipating Valve
Description:
A2A5 is a surge anticipation valve and could be adjusted to eliminate hazardous pressure surges typical of water hammer. A water hammer is caused by an abrupt shut off of a pump or quick closure of a main valve, causing a fast propagation of low-pressure front, followed by an extremely high-pressure back-wave. A series of pressure waves, each one composed of alternating low and high pressure is created within a few seconds. A2A5 is a piloted hydraulic valve activated by line pressure. The valve has two pilots, for high and low pressure. Under normal conditions the A2A5 is closed. The valve opens when the line pressure drops below a preset pressure, in anticipation to the following surge, and remains open until the fluctuations subside.
Features:
• No slam operation
• Simple and reliable design
• Easy installation and maintenance
• Low Resistance and high flow capacity
• Protection for sewage as well as clean water pumping systems
Service Fields:
For water system, irrigation system.
