Burkert Type 0312 - Manual

Operating Instructions Type 0311/0312
Design:
2-way solenoid valve, direct acting, normally closed (Circuit
function C), normally open (Circuit function D) or mixer
function (Circuit function E).
Seal Materials and Fluids handled:
See Table.
Fluid and Ambient Temperature:
For Hazardous Locations Div. 1 (T4 rated)
Max. Ambient Temperature
104 °F (40 °C)
Max. Fluid Temperature 194 °F (90 °C)
For Hazardous Locations Div. 1 (T6 rated)
Max. Ambient Temperature
104 °F (40 °C)
Max. Fluid Temperature 140 °F (60 °C)
For Hazardous Locations Div. 2 and Ordinary Locations:
See Table.
Pressure Range:
Maximum inlet pressure see label on valve.
Installation:
Before installing valve ensure that piping etc. is free of foreign
matter (metal fillings, seal materials, welding scale etc.). Instal-
lation as required but preferably with coil uppermost. Installation
in this position tends to prevent foreign matter remaining in core
tube (increased life). Do not put any loads on coil unit.
Type 0311: PTFE tape is recommended for sealing ports.
Mounting is accomplished by means of four M4 x 8 mm tapped
holes located on the valve underside.
Type 0312: Ports A (B) are coded on side of body. For common
pressure, align "A (B)" marking on valve and manifold. Valve
operation C and D valves cannot be manifolded together. To
remove valve from manifold loosen only the two unsealed screws.
Manifolds can be connected togehter with nipples.
