The needle valve continuously allows flow from the valve inlet into the upper control chamber [2]. Beramd pilot senses downstream pressure. Should this pressure rise above pilot setting, the pilot throttles, enabling pressure in the upper control chamber to accumulate, causing the main valve to throttle closed, decreasing downstream pressure to pilot setting.

Should downstream pressure fall below pilot setting, the pilot releases accumulated pressure, and the main valve modulates open. The integral orifice between the lower control chamber and valve outlet — valve reactions. The needle valve controls the closing speed. The downstream cock valve [4] enables manual closing. For 16″ and larger valves, see “Pilot Valve Selection” table at the last page.

MNFinal – Bermad

Engineer Specifications The Pressure Reducing Valve shall reduce higher upstream pressure to lower preset downstream pressure regardless of fluctuating demand or varying upstream pressure.

The main valve shall be a center guided, diaphragm actuated globe valve of either oblique Y or angle pattern design. The body shall have a replaceable, raised, bermaad steel seat ring.

The valve shall have an unobstructed flow path, with no stem guides, bearings, or supporting ribs. The body and cover shall be ductile iron. The actuator assembly shall be double chambered with an inherent separating partition between betmad lower surface of the diaphragm and the main valve.

The entire actuator assembly seal disk to top cover shall be removable from the valve as an integral unit. The stainless steel valve shaft shall be center guided by a bearing in the separating partition. The replaceable radial seal disk shall include a resilient seal and 7720 be capable of accepting a V-Port Throttling Plug by bolting.

The control system shall consist of a 2-Way adjustable, direct acting, pressure reducing pilot valve, a needle valve, isolating cock valves, and a filter.

The assembled valve shall be hydraulically tested and factory adjusted to customer requirements. The main valve shall be certified as a complete drinking water valve according to NSF, WRS, and other recognized standards.

The pump supplies water to the network and to the reservoir. System pressure is too high for the residential neighborhood, requiring a pressure reducing system. Protection against momentary pressure peaks Visual indication of need for maintenance By-Pass Pressure Reducing Valve saves on maintenance costs.


The larger more costly to maintain valve operates during peak demand. The smaller by-pass valve cuts operating hours of the larger valve, achieving greater return on investment. Supply cut-off is unacceptable and single source supply is common. Valves are hermad in areas where water damage can be extremely expensive.

Pressure reducing systems are often located next to prestigious residential and office space. Extraneous noise and maintenance activities are to be avoided. The main supply line of high-rise buildings is exposed to greater head at lower zones bedmad pressure for the consumer must be kept within recommended levels.

Parallel Redundant Branches ensuring uninterrupted supply by enabling unskilled personnel to temporarily shut off one of the branches. Pressure Switch [6] signals a control panel of excessive downstream pressure. Emergency Valve [2] is fully open during normal operation. Triggered by the control panel, it becomes a proportional pressure reducing valve.

In addition to the typical bermar zone installation, this high differential pressure system also includes: Proportional Pressure Reducing Bermadd -PD, as the first pressure reducing stage, absorbs part of the high differential pressure.

By spreading the load of pressure reducing onto two components, cavitation damage and noise are reduced.
