Re: Heater valve parts

Parker is just a brand of high quality hose and fittings that is normally associated with hydraulic hose but they do show heater hose.

That looks to be a bypass style valve that while shutting off the flow to the heater keeps the coolant circulating though the heater hose. Important for a couple of engines that we as a group use quite often but the exact ones slip my mind.

77 C 30 dualie, 454, 4 speed with a 10 foot flatbed and hoist. It does the heavy work and hauls the projects around.
