This is a 10-port replacement P-style sampling/switching valve with ⅛” fittings and 0.08” (2 mm) bore.
It is made of Hastelloy C, a versatile nickel-chromium molybdenum alloy that has excellent acid resistance, avoiding pitting, stress corrosion cracking, and oxidizing. The rotor is made from Valcon R, a PTFE composite used in low-temperature/pressure situations that require its nearly universal chemical inertness. It can be used at temperatures up to 75°C at pressures up to a maximum of 400 psi.
