PRODUCT DESCRIPTION

INTRODUCTION

The Philmac air release valve has been designed to allow air to be discharged from pipelines during filling to ensure there are no air pockets which reduce the flow of water. The valve is a kinetic type of valve which means it will expel air when a pipeline is filled but once sealed will expel no more air while the system remains pressurised.

They also admit air into pipelines during drainage to prevent possible pipe collapse due to a vacuum. The direction of air flow is clearly marked by an arrow on the body of the valve..

Philmac's air release valve can be connected to both plastic and metal threaded fittings. PTFE tape or an approved sealant is required.
