PRODUCT INFORMATION
Pressure Reducing Ratio Valve IR-120-PD-Z
The Bermad double chambered control valve is a ratio reduction valve that will reduce upstream pressure to downstream pressure at a Fixed ratio. The valve has a non metallic body and is simple and effective to reduce line pressure with no operating pilot mechanism.
APPLICATIONS:
- Pressure Reducing Stations
- Long downhill lines
- Serial pressure reduction
- Leakage and burst protection
- High differential pressure systems
- Protection against cavitation damage
- Throttling noise reduction

TECHNICAL DATA
OPERATION
The downstream pressure is applied as closing force on the top side of both
the diaphragm and the seal disk areas. The upstream pressure is applied as
opening force on the bottom side of the seal disk area. The net force, resulting
from the two opposing dynamic forces acting on the actuator’s diaphragm and
seal, determines the degree to which the valve is open. As the ratio of the areas
of the seal disk and the diaphragm is constant, the ratio of the upstream and
downstream pressures is constant as well. When demand is zero, downstream
pressure rises in proportion to the reduction ratio, causing the valve to shut off.
The Manual Selector Valve 1 allows manual closing of the valve
