Products Details
Material:
- Case: grey cast iron, cast aluminium
- Tube: rubber in various qualities and colours, depending on requirement and application area.
Design:
- The special tube valve SP P consists of the case, the scissor part and the drive. The elastic tube insert is compressed evenly using a scissor system. The clamping scissor is actuated using a pneumatic cylinder to which the control air is supplied via a 5/2 way solenoid valve.
Electrical Equipment:
The valve has a limit switch (normally closed contact and normally open contact) in each end position. A Herion 5/2 way solenoid valve is usually used as control valve (other makes of control valve on request). The electrical equipment is supplied in any protection type and any common voltage according to requirement.
Special features:
The complete tube cross section in the valve is enabled in the open position. No disruptive components are present; therefore only low abrasion and low pressure losses. The advantage of the design is that the tube is the only wear part and this can be replaced quickly. A further advantage is that leak tightness is already reached at equalisation of control and operating pressure and a separate control air network can be saved. The valve is closed in the event of power failure.
