These bleed valves are designed to vent high pressure or condensate from charging lines, filters, separators and other volumes where pressure must be relieved to disconnect lines, tanks etc. They have an exclusive seal design that permits opening and closing thousands of times without loss of sealing ability. Light finger pressure is all that's required however over torquing should not damage the valve. The model 1004 bleed valve has only one male NPT fitting so it is better suited for separator drains. The model 712 has two connections so is better suited for in line uses.
