The combination of this Y-shaped valve design and a large port gives the 400Y one of the highest flow capacities in its class.
The water is therefore able to take the shortest, straightest route through the valve to the outlet, with minimal head loss. This valve’s Y-shaped design positions the port at just a 20˚ angle to the flow direction.

Therefore the maximum flow rate can vary considerably from one make and model of a fire control valve to the next, depending on how well the valve is designed to facilitate flow.īecause it was specifically designed from the ground up for use in fire protection applications, the BERMAD 400Y Torrent Valve is engineered to have exceptional fire water deliverance capability. With every twist and turn the water must take to get through the valve itself and/or bypass obstacles within the valve, pressure is lost. Valve designs vary the angle of flow differs depending on model. However, when water flows through a valve, it must change direction to bypass the inner structure of the valve. Nearly any valve will do a good job of shutting off the flow. Valves by their very nature are designed to limit the flow of water. Valve construction, therefore, is a critical thing to consider when designing a fire protection system. Any obstruction at any point in the flow can reduce the effectiveness of the system’s performance. High flow capacity is essential for any water based fire protection system. A deluge valve body engineered for maximum flow capacity Now, let’s take a look at 4 additional features that make the 400Y uniquely efficient in its class. The 400Y’s valve diaphragm design is also exceptionally efficient in operation, offering first class opening reliability, virtually frictionless actuation, and an unobstructed flow-path. In a previous post, we examined this valve’s unique reinforced elastomeric diaphragm and explained how its construction results in exceptional durability-and of course a highly durable valve is also highly economical from a cost control point of view. The BERMAD 400Y Torrent Valve is designed from the ground up for optimal efficiency, both in an emergency situation and during normal, day-to-day operations and routine services. Over time, this can lead to substantially reduced cost of operations. System components designed for versatility and ease of use can save significant time during routine maintenance and servicing as well as installation. However, the need for efficiency is not restricted to emergency situations. Time is of the essence even a slight delay in fire water delivery could spell the difference between a contained event and one that spirals out of control. During a fire event, the need for efficiency in a fire protection system is absolute.
