Description

Overview

The SV-1 synchronising valve provides on off pneumatic control to delay or sequence devices in trailer air brake systems. The SV-1 synchronising valve suits applications where a defined pressure signal should open, close, then exhaust a circuit reliably. Consequently, fleets gain repeatable timing and simpler plumbing for staged functions.

Features

• Non-graduating on off action for clear, binary control
• Air-signal operated, suitable for automatic or non-automatic circuits
• Compact body suits tight mounting locations on trailers and dollies
• Standard pipe threads simplify integration with existing fittings

Specifications and Materials

Part number: AB8357.
Ports: supply 1/4″ NPT, delivery 1/4″ NPT, control 1/4″ NPT, exhaust 1/8″ NPT. Typical use: delay or sequence an auxiliary air circuit in a heavy-vehicle braking system. For technical background and service data, see the Bendix service data sheet SD-03-4020

Compatibility and Fitment

This cross-reference listing means this valve is a suitable replacement for the part numbers and applications shown. Some changes in air line plumbing may be required.

Compliance and Safety

Install and torque fittings to pneumatic standards, then leak-test with soapy water or an approved method. Finally, verify brake timing and release characteristics in a safe area before returning the vehicle to service.

Trailer Applications

Use the SV-1 synchronising valve to time lift-axle control, interlock release, or accessory actuation that depends on a defined pressure rise. Additionally, it can act as an automatic controller when supply and control are connected, enabling simple logic without electrical wiring.
