UPVC Dialock 2 Way Diaphragm Valve
The UPVC Dialock 2 Way Diaphragm Valve use to control and shut off filthy or scratchy substances. The body’s redesigned internal shape enhances flow coefficient and pressure drop, allowing for delicate, accurate shutter adjustment over the whole stroke.
The valve is quite small and lightweight. There is an ergonomic and quick locking feature on the handwheel, allowing the handwheel to be moved and secured in any position.
Many different materials, body styles, and diaphragms may be used with this FIP UPVC Dialock 2 Way Diaphragm Valve. Weir-style body re-design improves flow rate and allows for accurate linear flow regulation across the valve’s complete range of operation. There are a variety of choices and accessories available with this pneumatically operated variant.

It enhances the rate of flow. In addition, the PVC Dialock 2 Way Diaphragm Valve allows for accurate linear flow control. Through the use of its locking mechanism, the handwheel may be changed and secured to more than 300 places.
UPVC Dialock 2 Way Diaphragm Valve Product Advantages:
- UPVC Dialock 2 Way Diaphragm Valve inner body is processed by digital lath to ensure the seal of the threaded carrier.
- Each ball Valves to be polished after rough turning and fine-tuning to ensure its smooth and good performance in the seal.
- The body and hole of the stem should be processed by lath to assure the stability of the seal and to increase strength.
- The tooth of products (size bigger than 2-1/2 inch) are processed and finished by lathes to ensure the union cap and the body is assembled more closely.
- All valves were tested on pressure/hydro test before dispatch from our factory.
- The valve should be double blocking with union ends, locking of union nuts design ANTI-shocking.
- It comes with Electrics & Pneumatics actuated valve series.
- Connection system for solvent-welding and for flanged joints.
- Optimized fluid dynamic design: maximum output flow rate thanks to the optimized efficiency of the fluid dynamics that characterize the new internal geometry of the body.
- Handwheel that stays at the same height during rotation, with internal bearing to minimize friction and operating torque.
- Standard optical indicator.
- Internal operating components in metal are totally isolated from the conveyed fluid.
- Bonnet fastening screws in STAINLESS steel protected against the external environment by PE plugs.
- New flanged bodies: the new bodies, characterized by a monolithic flanged structure, are available in PVC-U, PVC-C, PP-H, and PVDF. This design, free from body and flange joints, greatly reduces mechanical stress and increases system performance.

UPVC Dialock 2 Way Diaphragm Valve Information
FIP UPVC Diaphragm DIALOCK Valve
FIP UPVC Diaphragm DIALOCK® valve is particularly suitable for shutting off and regulating abrasive or dirty fluids. The new internal geometry of the body increases flow coefficient, reduces pressure drop, and allows a sensitive and precise adjustment along the entire stroke of the shutter.
The DK is extremely compact and very light. The innovative handwheel is equipped with a patented immediate and ergonomic operating locking device that allows it to be adjusted and locked in any position.
• Connection system for solvent weld, threaded and flanged joints
• Optimised fluid dynamic design: maximum output flow rate thanks to the optimised efficiency of the fluid dynamics that characterise the new internal geometry of the body
• Internal components in metal, totally isolated from the fluid and external environment
• Modularity of the range: only 2 handwheel and 4 diaphragm and bonnet sizes for 7 different valve sizes
• Non-rising handwheel that stays at the same height during rotation, equipped with a graduated optical indicator protected by a transparent PVC cap with seal O-Ring
• Bonnet fastening screws in stainless steel protected against the external environment by PE plugs. Absence of metal parts exposed to the external environment to prevent any risk of corrosion.
• CDSA (Circular Diaphragm Sealing Angle) system that, thanks to the uniform distribution of shutter pressure on the diaphragm seal, offers the following advantages:
− reduction in the tightening torque of the screws fixing the actuator to the valve body
− reduced mechanical stress on all valve components (actuator, body and diaphragm)
− easy to clean valve interior
− low risk of the accumulation of deposits, contamination or damage to the diaphragm due to crystallisation
− operating torque reduction

The Kv 100 flow coefficient is the Q flow rate of litres per minute of water at a temperature of 20°C that will generate Δp= 1 bar pressure drop at a certain valve position. The Kv100 values shown in the table are calculated with the valve completely open.
RELATIVE FLOW COEFFICIENT GRAPH
The relative flow coefficient is the flow rate through the valve as a function of the degree of valve opening. Horizontal axis: Percentage opening
