Panel Brake System
The Tri-Plate Panel Mounted Brake System is mainly made out of Aluminium alloy plates specially machined and then sandwiched. These are used for compact assembly of brake valves thus saving the space as well as reduction of large number of pneumatic fittings. This is modular in concept as well as maintenance friendly.

Vacuum Console Panel is a compact unit housing the Vacuum Valves as well as the Filters and also a small panel comprising of other associated Valves related to Vacuum Brake System in the Locomotive. This eliminates dispersed fitment of Vacuum Valves in the Locomotive Brake System thus eliminating leakages as well as saving of space in the Locomotive.
 
 
  8" x 8" UAH Brake Cylinder
UAH Brake Cylinder is used for Locomotive Brake application. It develops forces due to outward movement of Piston due to air pressure. The Brake Cylinder includes a Piston and Push Rod so designed that when it is connected to suitable brake rigging it will provide brake force through the rigging. This can be supplied in 9" and 10" dia version depending on customer's requirement

  A-9 Automatic Brake Valve
The A-9 Automatic Brake Valve is a compact self lapping, pressure maintaining Brake Valve which is capable of graduating the application or release of locomotive and train brakes. A-9 Automatic Brake Valve has five positions: Release, minimum Reduction, Full Service, Over Reduction and Emergency.
 
 
  SA-9 Independent Brake Valve
SA-9 Independent Brake Valve is a compact self lapping, pressure maintaining Brake Valve which is capable of graduating the application or release of Locomotive Air Brakes independent of Automatic Brake. The SA-9 Independent Brake Valve is also capable of releasing an automatic brake application on the Locomotive without affecting the train brake application. The SA-9 Brake Valve has three positions : quick release, release and application

  VA-1 Release Valve
The VA-1 Release Valve without choke is used as a remote controlled cut out cock. It is installed in the Vacuum Brake pipe line between the VA-1B Control Valve and the Train Vacuum Brake pipe.
 
 
  H-5 Relay Air Valve
The H-5 relay air valve is an air operated three way valve that changes the air passage through it when the control air pressure is vented to atmosphere
  Top
 
  HB-5 relay Air Valve
The HB-5 relay Air Valve is a pneumatic, double piloted, three way valve that changes the air passages through it when air pressure of a predetermined amount or more is in the control chamber
 
 
  HS-4 Control Air Valve
The HS-4 Control Air Valve delivers a regulated, uniform, predetermined air pressure, which usually serves to regulate the operation of another device in the brake System
  Top
 
  F-1 Selector Valve
The F-1 Selector Valve performs the function of commanding the brake equipment on the locomotive to lead or trail position of the adjacent locomotive and ensures operation of brakes in the trail locomotives when initiated from the lead locomotive
 
 
  A-1 Differential Pilot Air Valve
The A-1 Differential Pilot Air Valve is designed to activate a number of pneumatic devices for a predetermined length of time even though it's control air supply is maintained for a considerably long period
  Top
 
  C2W Relay Air Valve
The C2W Relay Air Valve is a diaphragm cooperated self lapping valve having higher capacity which is used as a remote controlled pneumatic device to relay a large quantity of main air reservoir pressure to the operating system for brake application
 
 
  MU-2B valve
The MU-2B Valve is a manually operated, two position and multi-ported valve arranged with a pipe bracket and is normally used for locomotive brake equipment for multiple unit service between locomotives equipped with similar system in conjunction with F-1 Selector Valve
  Top
 
  VA-1B Control Valve
The VA-1B Control Valve proportions the amount of vacuum in the vacuum brake pipe to the air pressure in the compressed air brake pipe on the locomotive and acts as a pilot valve to operate the train vacuum brake, thus securing an application simultaneously with, and in proportion to the locomotive air brake application.
 
 
  D-1 Emergency Brake Valve
The D-1 Emergency Brake Valve is a manually operated device which provides a means of initiating an emergency brake application
  Top
 
  J-1 Safety Valve
The J-1 Safety Valve installed vertically in the main reservoir system vents pressure at a predetermined setting to atmosphere in order to prevent excessive main reservoir pressure buildup
 
 
  D-1 Automatic Drain Valve
The D-1 Automatic Drain Valve automatically discharges precipitated moisture from reservoir with each operating cycle of the control device. The drain valve may be installed on main reservoir with a sump
  Top
 
  D-24 B Feed Valve
The D-24 B Feed Valve is a large capacity highly sensitive relay valve which is designed to direct the flow of air under pressure to various devices in air brake equipment arrangement at a predetermined pressure
 
 
  Duplex Check Valve
Piston type duplex check valves are generally used in Railway Compressed Air Brake systems to prevent excessive use of auxiliary equipment from depleting the main compressed air supply to the detriment of the brake equipment
  Top
 
  24-A Double Check valve
The 24-A Double Check Valve is used to permit a device to be controlled by either of two other devices
 
 
  AB Test Rack
This is a composite test rack where all the WABCO Brake Valves can be tested by using separate test plates for individual Brake Valves
  Top
 
  Tread Brake Unit type BF2S
Tread Brake Unit type BF2S as per SAB-WABCO design is a very compact device integrating entire brake actuating mechanism for Railway vehicles comprising of Brake Cylinder, Levers for magnification of Braking efforts, Slack Adjuster to keep Cylinder stroke constant irrespective of Brake Shoe Wear and Brake Shoe Holder with twin Brake Blocks
 
 
  C3W Distributor Valve as per SAB WABCO Design
C3W Distributor Valve is a graduated release UIC approved Distributor Valve for application in the Coach Brake System used for initiating the brake application. These valves are supplied in Aluminium version as well as Cast Iron version as far as Body, Top covers and Bottom Covers are concerned
