    All Px inputs are .040 inch(1.067mm) bulged tubulations. These tubulations are designed to accept any .042 inch tubing manufactured by Scanivalve Corp. Each sensor pack valve block contains eight (8) or, in the duplex version, sixteen(16) Px inputs. ZOC33 modules are capable of mea- suring pressures up to 50 psid.
