L STYLE WATER HAMMER ARRESTER ► The flow-directing mechanism in the valve can guide the flow and stabilize pressure. ► In the corner of pipe, the water hammer is the most obvious. The design is for meeting the requirement and set the arrester at the corner directly. This design not only saves the space and is easy to set up, but also can replace the traditional crooked head to reduce the cost of setting up. ► L style absorbs water hammer effect in two ways and brings excellent result. ► Applied conditions: Fluid ► Diaphragm material: NBR & Viton ► Normal air chamber pressure: 2.5 kgf/cm2 ► The test pressure of valve body: Cast Iron & Bronze: 21 kgf/cm2 ► Maximum applied pressure: SSteT Cast Iron & Bronze: 12 kgf^m2 air-pumping hole

THE INSTALLATION CONDITIONS OF L STYLE WATER HAMMER ARRESTER When pump shuts off, pressure decreases instantly and forms unstable gap of positive and negative pressure that causes water hammer effect and creates noise and pipe vibration. To set up water hammer arrester at the pipe corner upside of the pump (shown as the figure) can prevent the water hammer effect and protect the machine. When lift is longer than 50m and pressure is above 5 kgf/cm2, we suggest to set up arresters each at the downside of the long pipe and the upside corner of the check valve.
