It really depends on the fluid you use in the heat pipe, but any valve that is rated for steam should work and there are alot of steam valves out there for heating systems that have servos on them so it could be set up as an automatic system.

If you simply coiled some metal tubing around the exhaust pipe, insulated it, and put the valves in the pipe (vs. any flexible heater hose you might use for routing), I'd think you'd be OK with pressure issues.
