Evaluation of valve closure via the contact heating method over a wider temperature range. (A) When pressure and time were held constant (336 ± 75 psi and 3 s, respectively) and as stylus temperature exceeded 230 °C, a sharp increase in channel closure success was noted. (B) Broadly speaking, this effects plot visualization of the generalized linear model suggests a rapid increase in the probability of successful closure as stylus temperature increases from 200 to 270 °C.
