Diesel Engine Air Intake Shutoff Valves
Model RDS1 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 an explosion.
The Roda Deaco RDS1 Swing Gate Valve is a compact air intake shutoff valve that provides emergency overspeed shutdown of a diesel engine. The RDS1 Swing Gate Valve can be triggered to close, which starves the engine of air and shuts down the engine.

Operation
The Model RDS1 is a compact swing gate design air intake shutoff valve available with either electric or mechanical actuation. Actuation of the Model RDS1 closes the valve’s sealing element which shuts off intake air flow into the engine. The RDS1 can be used in fully automatic or manual shutdown systems.
Refer to the Roda Deaco Selection Guide to determine the appropriate system and actuation for your application.

Valve Selection
The RDS1 Swing Gate Valve is available in several standard sizes for intake air lines ranging from 11/2 to 2 inches (38 to 51 mm) in diameter. Standard sizes for hose and V-clamp attachments are listed to the left. Additional sizes are available to meet specific application requirements.
Standard Attachment Sizes
1 1/2” 38 mm
1 5/8” 41 mm
1 3/4” 44 mm
1 7/8” 48 mm
2” 51 mm
The RDS1 Swing Gate Valve can be used in applications where the air intake line is 1/2 to 2 1/2 inches (15 - 65 mm) in diameter. The RDS1 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.
To accommodate the installation requirements for the wide variety 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, flange, and engine specific attachment.

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.
Special AttachmentsAdditional attachments are available on request.

Valve Features Selection
Valve Actuation TypeThe Diesel Engine Air Intake Shutoff Valve has two actuation methods: 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 RDS1 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 RDS1 valve is designed for use in the systems indicated below:
l Automatic Electric Overspeed RPM Detection with Manual Override
l Manual Electric System
Mechanical Actuation
The mechanically actuated RDS1 can be operated by using either a remote cable pull system or direct operator action on the valve. The mechanically actuated RDS1 is reset manually. The mechanically actuated RDS1 valve is designed for use in the systems below:
l Remote Cable Pull Actuated System
l Direct Actuated Valve
The RDS1 Swing Gate Valve can be used on intake lines of naturally aspirated or turbo-charged engines where air intake line temperatures do not exceed 221°F (105°C) at the valve.
Valve Intake Air Temperature Rating
Temperature range
Standard range -40°F to 221°F -40°C to 105°C
Pneumatic Reset
A pneumatic cylinder can be added to the valve to provide remote reset capability for mechanically actuated valves.
