4" AND 6" MODEL RCW WATER CONTROL VALVE FOR DRY, PREACTION AND DELUGE APPLICATIONS

Globe is proud to introduce the new Model RCW Water Control Valve for dry pipe, preaction and deluge applications.

It is uniquely engineered to minimize many of the field issues historically seen with hydraulically operated differential-style valves. All system types use one common valve body — and its lighter weight and smaller size make it easier and faster to install.

1 VALVE 10 TRIM CONFIGURATIONS• One valve comes in 10 different cULus-Listed/FM-Approved

trim configurations, lowering your inventory costs.

• The 4" and 6" RCW is lighter than any other manufacturer’s valve currently on the market. In each trim configuration, it is lighter than other makers’ versions.

• The RCW has the shortest end-to-end dimensions of any water control valve on the market.

• Double-seat design means no additional check valve is needed for preaction systems.

• Single-bolt clapper seal replacement, easy access to hinge pin and minimal bolts for handhole cover removal make the RCW easier to maintain and inspect.

• Diaphragm-to-clapper latching mechanism uses our unique, patent-pending “roller arm” design, offering lower friction loss and ensuring dependable performance unimpeded by corrosion or debris.

SHORTER. LIGHTER. MORE VERSATILE.

As an installer, you need only stock one valve for a variety of different system configurations. The RCW’s compact design makes it lighter and shorter in size than any other comparable valve on the market. This makes installation easier and, often, faster. The completed assembly takes up a smaller footprint in the building. The RCW’s double-seat design means no additional check valve is required. And you are backed by Globe’s renowned customer service and technical support every step of the way.

ONE VALVE. MANY APPLICATIONS.

The Globe RCW Water Control Valve — and each of its trim options — have been engineered to meet the most important needs of both the installer and end user.

The RCW is designed to perform. Its diaphragm-to-clapper mechanism is a unique new design featuring a low-friction roller arm. It uses a positive action spring force to assist movement of the diaphragm away from the clapper when diaphragm chamber water pressure is evacuated. Coupled with the minimal movement of the roller assembly, this results in faster operation on pressure drop and more dependable operation. The robust design allows for free movement of the lever arm assembly, even if debris or corrosion are present.

The RCW is a differential latching valve with a convenient external reset knob. Internal inspections and maintenance are easier, thanks to unique features such as one-bolt clapper seal replacement and easy handhole cover removal. And color-coded handles make it easy to identify, at a glance, if trim valves are in their proper positions.

DRY SYSTEMS

Dry Pipe Systems

Dry pipe sprinkler systems are typically used in unheated areas and other locations exposed to freezing temperatures, where water-filled pipe cannot be used. When set for service, a dry pipe sprinkler system incorporating automatic sprinklers (closed) is pressurized with air or nitrogen. In response to heat from a fire, an operated automatic sprinkler causes a loss of air pressure and permits the dry pipe valve to open. This allows a flow of water into the sprinkler system piping.

Dry systems are used in any unheated portion of a building:

• Warehouses

• Loading Docks

• Unheated Attic Spaces

• Shipping Platforms

• Cold Storage

• Parking Garages

• Outdoor Piers

• Unheated Attic Spaces

Robert C. Worthington was a pioneer in fire sprinkler system engineering, with a long and successful career before he purchased Globe in 1988. Mr. Worthington made a commitment to producing a high-quality product in the U.S. This valve is named in honor of his spirit of innovation and his life-long dedication to saving lives and protecting property from fire.

DELUGE SYSTEMS

SINGLE INTERLOCK PREACTION SYSTEMS

Deluge systems are used for special hazards where there are easily ignitable and fast-burning substances which promote rapid fire development. They are typically used for fire extinguishment, fire control or exposure protection in applications such as:

Single interlock preaction systems are used in any portion of a building where it is undesirable to have water-filled pipes over the hazard being protected. Such systems typically employ air or nitrogen under pressure, with a supplemental detection system installed in the same area as the sprinkler system.

• With materials having high rates of heat release

• Conveyors

• Water Curtains

• Fuel Storage Tanks

• Electrical Transformers

• Aircraft Hangars

• Chemical Plants

Electric Actuation

Single Interlock Electric Actuation

Dry Pilot Actuation

Single Interlock Dry Pilot Actuation

Wet Pilot Actuation

Single Interlock Wet Pilot Actuation

These valves are activated by a single event, an electrical detector activation, an activation of a pilot sprinkler connected to pilot lines under air pressure (dry pilot), or an activation of a pilot sprinkler connected to pilot lines under water pressure (wet pilot). They are commonly used in:

• Computer Rooms

• Archives• Libraries

• Document Storage Centers

Double interlock preaction systems are used in any portion of a building where flooding or inadvertent discharge of water would be especially damaging. These valves are activated by two separate events: an electric activation plus a sprinkler activation.

In the case of Electric/Pneumatic Actuation, a detector activation sends an electrical signal to the release panel, opening a solenoid valve. This event would typically be followed by a sprinkler activation, releasing air pressure in the sprinkler piping, allowing the pneumatic actuator to open, and tripping the RCW valve.

The simplicity and versatility of the Globe RCW make it an excellent choice for every application. With it, it’s truly “one and done.”

DOUBLE INTERLOCK PREACTION SYSTEMS

In the case of Electric/Electric Actuation, a detector activation will send the first electrical signal to the release panel. The activation of a sprinkler will allow air pressure in the sprinkler piping to escape, activating a low air pressure switch. This sends a second signal to the release panel, which opens the solenoid valve, tripping the RCW valve. They are commonly used in applications such as:

• Freezers

• Valuable Archives

• Critical Document Storage

Double Interlock Electric/Pneumatic Actuation

GENERAL DESCRIPTIONThe Globe Model RCW* Water Control Valve is a hydrau-lically operated external resetting differential latching style valve designed for use where quick-opening and total flood-ing of sprinkler system piping is desired. It is used as an automatic water control valve in Deluge, Dry Pipe, or Preac-tion systems, as well as foam-water sprinkler systems.Setting of the Model RCW Valve requires water pressure in the diaphragm chamber provided via a connection from the main water supply from a point upstream of the system main control valve, through a restricted orifice. Water pressure on the diaphragm is transferred to the plunger rod which forces the roller arm mechanism against the clapper, preventing the supply water from entering the sprinkler system piping. Actuation (tripping) of the Model RCW Valve is accom-plished by releasing water from downstream of the re-stricted orifice. Water pressure release can be caused by a va-riety of types of actuation trim and devices. For example the supply can be fed to a line of wet pilot sprinklers for wet pilot type Deluge or Preaction systems. Other devices which can be used for valve actuation include a dry pilot actuator, or an electric solenoid valve with an as-sociated releasing control panel.

Clapper Facing. The rubber clapper facing should be checked for wear or damage to determine that it is free of dirt and other foreign substances. If found to be worn or

damaged (e.g., foreign matter embedded in the surface), the facing should be replaced. If it is dirty, it should be cleaned. Compounds which could damage the rubber fac-ing must never be used.Seat Ring. The seat ring should be checked for nicks and for stones, dirt or other foreign matter lodged in the grooves or holes. It should be cleaned thoroughly. If the seat ring is found to be damaged, valve should be replaced.
