Burkert Type 0331 - Manual

Operating Instructions Type 0330/0331
Design:
2-way solenoid valve, direct acting, normally closed (Circuit func-
tion A), normally open (Circuit function B).
3-way solenoid valve, direct acting, normally closed (Circuit func-
tion C), normally open (Circuit function D), mixer function (Circuit
function E) or diverter function (Circuit function F).
Seal Materials and Fluids handled:
See Table1.
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. 2 and Ordinary Locations:
See Table1.
Pressure Range:
Maximum inlet pressure see label on valve.
Type 0330: 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 0331: Ports A (B) are coded on side of body. For common
pressure, align "A(B)" markings on valve and manifold. Valve ope-
ration C an D valves can be mounted on the same manifold but the
manual override buttons will point in opposite directions.
To remove valve from manifold loosen only the two unsealed
screws. Manifolds can be connected together with nipples.
Blanking plugs, Order No. 0315-1016, should be screwed into
the unused ports. Manifolds can be fixed in position using M5
screws.
Manual override:
The manual override can be retained in position if, after depressing
the button, it is turned in a clockwise direction.
Assembly instructions:
The conduit connector on the coil (4) must be supported against
torque during the assembly using appropriate tools (1) (i.e. pliers,
gripper...) (for example a gripper).
While tightening for example a fitting (3) into the conduit connec-
tor attention must be paid to the fact that a max. torque of 20Nm
(177lbf in) is not exceeded.
