Note: This diaphragm valve cannot be used for drinking water.

PVC diaphragm valve consists of a UPVC or CPVC body with an inlet and outlet and a diaphragm that separates these two ports. When the valve is in the closed position, the diaphragm seals against the body, preventing the flow of fluid.

Tips: Difference between a butterfly valve and a diaphragm valve

Butterfly valves and diaphragm valves are both types of flow control valves used in various industries. The primary difference lies in their design and operation:

Butterfly Valve:

A butterfly valve has a disc-shaped closure element that pivots around a central axis to control flow.
It operates by turning the disc 90 degrees to either fully open or close the flow passage.
Offers quick and efficient flow control with a low pressure drop.
Suitable for applications requiring on/off or throttling control, such as in HVAC systems and large water pipelines.
Relatively lower maintenance requirements and cost-effective.

Diaphragm Valve:

A diaphragm valve uses a flexible diaphragm or membrane to isolate the flow stream from the valve body.
It controls flow by compressing or retracting the diaphragm to allow or block fluid passage.
Ideal for applications requiring a high level of containment or purity, such as in the pharmaceutical and chemical industries.
Provides excellent sealing, preventing cross-contamination and leakage.
Generally more complex and expensive than butterfly valves, with higher maintenance requirements.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
