Purge Valve Stuck

I'm trying to drain the water in my boiler but the purge valve won't turn and I'm afraid of breaking it if I apply pressure in the wrong direction. I've attached images of the valve. Is anyone familiar with them? Should I be turning them clockwise or counterclockwise? I would greatly appreciate any help.

With more than thirty years in powerplants of various sizes I have only seen ONE valve that turned clockwise to open and that was the atmospheric exhaust for a steam turbo-generator in a plant that was built in 1920.

So to answer your question, turn it like an analog clock running backwards to open the valve. You might need some pliers.

A hint, buy some brass garden hose caps (and washers if the caps don't have them) and screw onto the hose threads of those valves. That way even if the valve leaks slightly the system is still sealed.

Push in when you turn them.

Does pressure inward need to be applied as they turn? Why else would they be spring loaded that way?

Edit: Sorry, missed guyold's reply.

Were you able to get them open?
