PVDF (Polyvinylidene fluoride) double union diaphragm valves are a type of industrial valve widely used in various applications, especially in industries that require resistance to corrosive and high-purity fluids. These valves are known for their exceptional chemical resistance, durability, and reliability.
Construction and Working Principle:
PVDF double union diaphragm valves consist of a body made of PVDF, a resilient diaphragm, and a handwheel or actuator for operation. The PVDF construction makes these valves resistant to a wide range of corrosive chemicals and fluids. The double union design allows for easy installation, maintenance, and removal without interrupting the pipeline.
The working principle of a diaphragm valve involves a flexible diaphragm that acts as a sealing element. When the handwheel or actuator is operated, it controls the movement of the diaphragm, allowing or blocking the flow of fluid through the valve. The diaphragm provides a tight seal against the valve seat, preventing any leakage.
Advantages of PVDF Double Union Diaphragm Valves:
Chemical Resistance:
PVDF is known for its excellent resistance to a wide range of corrosive chemicals, acids, and bases. PVDF double union diaphragm valves can handle aggressive fluids without corroding or degrading, making them suitable for applications where chemical compatibility is critical.
Durability and Longevity:
PVDF is a highly durable material, capable of withstanding harsh operating conditions, high pressures, and temperature extremes. PVDF double union diaphragm valves offer long service life and require minimal maintenance, reducing downtime and overall costs.
Leakage Prevention:
The diaphragm design of these valves ensures a reliable and bubble-tight seal, preventing any leakage. The resilient diaphragm material provides excellent sealing properties even in low-pressure or vacuum applications.
Versatility:
PVDF double union diaphragm valves are versatile and can be used in a wide range of industries, including chemical processing, water treatment, pharmaceuticals, semiconductor manufacturing, and food and beverage. They are suitable for both corrosive and high-purity fluid handling applications.
Features
With the birth of the company, we produced the first plastic diaphragm valve in 1979 and obtained certification from the Ministry of Chemical Industry in 1983.
The Diaphragm valve uses a high-quality sealing material, exhibiting ower compressive strain, for its diaphragm and cushion, resulting in optimum sealing performance.
The Diaphragm valve is designed so that pressure is distributed evenly. This design allows the hand-wheel torque to be reduced and maintains shut-off at low torque.
