Diesel Engine Air Intake Shutoff Valves

Model RDS3 Swing Gate Valve

Overview

If flammable gas or vapor is present in the atmosphere surrounding a diesel engine, it can be ingested into the engine and become an ungoverned fuel supply. This ungoverned fuel can result in runaway engine overspeed potentially leading to dangerous mechanical failure or explosion.

The Roda Deaco RDS3 Swing Gate Valve is a positive spring actuated air intake shutoff valve that provides emergency overspeed shutdown of a diesel engine. The RDS3 Swing Gate Valve can be triggered to close which starves the engine of air and shuts down the engine.

Operation

The Model RDS3 is a compact swing gate design air intake shutoff valve available with electric, pneumatic, or mechanical actuation. Actuation of the Model RDS3 closes the valve’s sealing element which shuts off intake air flow into the engine. The RDS3 can be used in fully automatic or manual shutdown systems.

Refer to the Roda Deaco System Selection Guide to determine the appropriate system and actuation for your application.



Valve Selection

The RDS3 Swing Gate Valve can be used in applications where the air intake line is 3 to 4 1/2 inches (76 - 114 mm) in diameter. The RDS3 Swing Gate Valve can be mounted in vertical or horizontal orientations and airflow through the valve can be in either direction.

When specifying the valve note the clearance requirements for the valve with the geometry of the engine and intake line for your application. Note that the valve reset handle is used only on the mechanical and pneumatic actuated valves. The reset handle is not required on the solenoid actuated valve.

To accommodate the installation requirements for the wide variety of diesel engine applications, the size and attachment types on the valve body and the valve cover are specified separately. The valve attachments are available in several styles including: hose, O-ring, V-clamp, flange, and engine specific adapters.

Valve Size

The RDS3 Swing Gate Valve is available in several standard sizes for intake air lines ranging from 3 to 4 inches (76 - 102mm) in diameter. Standard sizes for hose, V-clamp, and O-ring attachments are listed to the left. Additional sizes are available to meet specific application requirements.

Valve Attachment Mechanism

The hose attachment is the standard attachment mechanism. However, additional attachments are available including O-Ring, V-Clamp, Flange, and engine specific adapters. Examples are

shown below. To accommodate the installation requirements for the wide variety of diesel engine applications, the size and connection types on the valve body and the valve cover are specified separately.

Hose Attachment

Uses sections of flexible hose and band clamps to attach the valve to intake line.

V-Clamp AttachmentHeavy duty V-style ring clamp used to clamp valve to metal intake lines. Several types of V-clamp connections are available.

O-Ring AttachmentSpace saving single or dual O-Ring attachments are available. O-Rings are used to seal rigid air intake line connections.

Flange AttachmentFlange attachments on the valve are available to secure the valve to the engine.

Valve Actuation Type

Pneumatic Actuation

Electric Actuation

Mechanical Actuation

The RDS3 Diesel Engine Air Intake Shutoff Valve valve has three actuation methods: pneumatic, electric and mechanical. Please refer to the Roda Deaco System Selection Guide for complete descriptions of the systems to help determine the proper actuation required for your application.

Electric Actuation

The electrically actuated RDS3 is an energize-to-close valve. It operates using either 12 VDC or 24 VDC power. The valve will automatically reset after the engine stops and power is removed. The electrically actuated RDS3 valve is designed for use in the systems indicated below:

l Automatic Electric Overspeed RPM Detection with Manual Override

l Manual Electric System

Pneumatic Actuation

The pneumatically actuated RDS3 is designed for mechanical latching in the open position (engine run) and air pressure actuated closure. The pneumatically actuated RDS3 is reset manually.The valve is designed for use in the systems indicated below:

l Automatic Electric Overspeed RPM Detection with Pneumatic Actuation

l Manual Electric/Pneumatic System

l Manual Pneumatic System

Mechanical Actuation

The mechanically actuated RDS3 can be operated by using either a remote cable pull system or by direct operator action on the valve. The mechanically actuated RDS3 is reset manually. The valve is designed for use in the systems indicated below:

l Remote Cable Actuated System

l Direct Actuated Valve



Valve Features Selection Continued

The RDS3 Swing Gate Valve has three air intake temperature range options to accomodate various installation locations:

lStandard - natural aspirated or downstream of turbocharger intercooler or aftercooler where air intake line temperatures may reach up to 221°F (105°C) at the valve

lHigh - downstream of turbocharger where air intake line temperatures may reach up to 400°F (204°C) at the valve

lXHigh - downstream of turbocharger where temperatures may reach up to 550°F (288°C) at the valve

Valve Intake Air Temperature Ratings

Temperature range

Standard range -40°F to 221°F -40°C to 105°C

High temperature -40°F to 400°F -40°C to 204°C

XHigh Temperature -2°F to 550°F -19°C to 288°C

The RDS3 Swing Gate Valve has two options that can be added individually or in combination to meet the additional requirements for applications.

Pneumatic Reset

A pneumatic cylinder can be added to the valve to provide remote reset capability for pneumatically and mechanically actuated valves.

Proximity Switch

A proximity switch can be added to provide indication of the position of the swing gate disk. This is very useful in multiple valve applications such as twin intakes to provide status indication of both valves in the system to prevent operation on a single bank of cylinders in an engine.

Valve Features Options

Pneumatic Reset

Proximity Switch

proximity switchThe purchaser and end user are solely responsible for analyzing all design aspects of their application, and the selection, use, and maintenance of the switch system. This includes provisions to mitigate potential fault and failure conditions in wiring and switch. A switch system that is improperly wired, tested, or maintained can cause progressive engine damage.



Actuation Kits

Actuation kits are provided with each system sold. The actuation kit contains hardware required to properly install and integrate the specified shutdown system into the diesel engine application. The kits, specific for each type of system and application, can include items such as:

l Voltage control module

l Relays

l Circuit breaker

l Toggle switch

l Cable with T-handle

Installation kits are also provided with each system sold. The installation kit contains the hardware required to facilitate the installation of the Air Intake Shutoff Valve into a diesel engine air intake line. Roda Deaco has hundreds of different installation kits designed to meet specific engine model and application requirements. The kits can range from hose with clamps to custom intake pipes, elbows, flanges, brackets, etc.
