JD pinch valves are ideal solutions where shut-off and control applications involve abrasive or corrosive slurries, muddy sediment, silty liquid powders or coarse substances.
The number of design variations is virtually unlimited as the modular structure of a JD valve enables the selection of any actuator, valve body construction and sleeve material to fit specific process conditions.
JD Pinch valve is simple. In the open position, the valve is at full bore with no flow restrictions thus making the valve an integral part of the pipeline. During closing, two pinch bars squeeze the sleeve shut on the centerline. The JD valves provide a 100% tight shut-off.
Manually Operated Pneumatically Operated
Modular Design of the Pinch Valve
JD modular pinch valve design has three main components: the sleeve, the body and the actuator (manual, pneumatic, and electric). The sleeve is the only part that is in contact with the process medium. The construction and materials of all three main components can be tailored to suit most process conditions. Self-cleaning JD CONTROLS valves provide 100% tight shut-off even if solids have built up on the sleeve wall. When compressed, any crystallized particles flake off the sleeve surface and are washed downstream.
JD pinch valves are particularly suitable for the process industry for shut-off and control applications.JDC provides pinch valves with open, sealed and general line valve bodies. We provide tailor-maid flow control solutions precisely in accordance with the customer specification.
- Size range: Standard range from 25 mm( 1”) to 350mm(14”)
- Temperatures: 50°C to +160°C
- Operating pressures: Vacuum to 100 Psig
JD-Pinch valve offers the following benefits:
- durability in demanding conditions
- Long service interval, low cost
- No blocks because of structure, reliability
- Can be tailored to the different needs
Typical users are:
- Mines and concentrator
- Wastewater processes
- Chemical industry
- The energy industry and power plants
- Pulp and paper mills
- Grain storage, loading, unloading (rubber sleeve for food)
As a small manufacturer, we are agile and we can manufacture valves tailored to customer needs. The design, actuator, positioner, and sleeve are completely modifiable so you don´t have to make any compromises. The frame Can be galvanized and powder coated.
Actuator: Pneumatic actuator controlled by magnetic valve or positioner from finish manufacturer
Flange borings: Full size flange with flange borings, DIN or ANSI -standard. Frange borings have been galvanized and powder painted
Sleeve: Is made of natural rubber with textile reinforcements. The sleeve is only part which is contact with the flowing material. Sleeve can be eaily changed.
Press section: The positioner guides the press section of actuator into wanted position to control the flowing.
Positioner/Magnetic valve: Controls the actuator. Magnetic valve opens or shut down the flowing. The place of positioner can be tailored.
Opening stripes: Have been attached in to press section. This secures that the sleeve will open in every situations.
