hey fellas just wondered what you fellas say the answer is to this and why if yo dont mind thanks alot
The operating forces in a txv/tev are.
(bulb pressure+spring pressure) versus(refrigerant pressure
(bulb pressure+refrigerant pressure) versus(spring pressure)
(spring pressure+superheat)versus(bulb pressure)
(spring pressure+refrigerant pressure)versus(bulb pressure)
thanks alot

I'd go for C i know im probably wrong but.... well at least i tried:p
Edit just been thinking about it and Bulb Pressure should be equal to Refrigerant Pressure + spring Superheat so i would now say the answer is D.
In a TXV, the forces need to be balanced for it to be stable.

D, why ? http://images.google.be/imgres?imgurl=http://www.hvacmechanic.com/images/txv.gif&imgrefurl=http://www.hvacmechanic.com/txv.htm&h=279&w=560&sz=21&hl=nl&start=3&tbnid=ebZRp5nL71dfjM:&tbnh=66&tbnw=133&prev=/images%3Fq%3Dtxv%26gbv%3D2%26svnum%3D10%26hl%3Dnl%26sa%3DG

Im still saying D
Evaporator Pressure + Spring Pressure = bulb pressure
