Chalwyn Valve to fit diesel/petrol driven engine pumps.

Flammable gas or vapour drawn into a diesel engine intake acts as an ungoverned fuel supply, causing uncontrolled over-speed and mechanical failure or flashback ignition of the surrounding flammable atmosphere. An air intake shut down valve is the only certain way to stop the engine.

Chalwyn D Series valves have the advantage of providing cost-effective fully automatic engine over-speed protection with the simplicity of no requirement for mechanical or electrical connections. Different size ranges have allowed meeting application requirements for virtually all popular intake pipe sizes and engine ratings.

Chalwyn stainless steel diesel engine spark arrestors are approved to EU ATEX standards and are of the quenching type to provide essential safety wherever a stray spark may cause ignition of combustible material. Glowing particles emitted from a diesel engine exhaust are repeatedly impacted against internal spark arrestor surfaces to be cooled and broken down before eventual discharge to atmosphere.
