Valve control for heating and air conditioning systems has temperature fixing devices positioned inside valve housing and strap passed around housing with studs which are inserted into holes in valve housing to contact fixing devices

摘要

The valve control has a spring-biased plunger (5) and a temperature responsive expansion component with a piston (13) above the plunger. Fixing devices (9,10) are positioned inside the valve housing (15). A strap is passed around the housing and studs (17, 18) on its ends are inserted into holes (16) in the valve housing so they contact the fixing devices.
