Water hammer relieving Check valve mechanism is provided in the E side of the supply orifice D and E and supply into the pressure action chamber B can be controlled with two stages by moving the diaphragm assembly r. After release of the energy, when the open amount of the main valve C becomes small, E is blocked. A low valve closing speed relieves the water hammer.

Consider q Max. payload, w static moment, e dynamic moment (when stopper collides) when calculating the Max. allowable moment and payload. Evaluate q and w as a (average speed), and e as (collision speed =1.4a). Calculate q (Wmax) from the graph of Max. payload (W1, W2, W3) and calculate w and e (Mmax) from the graph of Max. allowable moment.
For AC voltages add 1g to the weight of the single solenoid and 2g to the weight of the double solenoid and 3 position types.
