Thermo compact Fill control valve, dedicated DIN with Yoke adaptor. Made from high-quality chrome plated brass
 
These fill valves are very high quality at a good price. They come with twist or push bleed pressure release options and can be purchased with or without a gauge (if purchasing without a gauge, a port plug will be installed in place of the gauge).
 
The female inlet port is 1/4" NPT. A connection nipple can be added to this port to suit your current hose connection set up.
 
Add a Thermo High Pressure Swivel (SKU# CV604) for the ultimate fill valve. The addition of the HP swivel allows the fill valve to rotate 360 degrees under pressure which stops the iconic hose wrestling associated with fill valve connections.
