What Are Sanitary Diaphragm Control Valves?
Design and Function
You use sanitary diaphragm valves to control the flow of liquids in clean environments. These valves have a simple design. Diaphragm valves use a flexible membrane to control the flow of fluids through process lines. Turning the valve handle clockwise lowers the diaphragm to decrease flow. A flexible diaphragm presses against the valve body to stop flow or lifts to let liquid pass. For secure, leak-proof connections, tri-clamp fittings are commonly used in sanitary diaphragm valves.
Clamps are essential accessories for ensuring tight, hygienic connections and ease of maintenance, making assembly and disassembly straightforward. You can choose from manual, pneumatic, or electric actuators, depending on your needs. The valve body often uses stainless steel for strength and resistance to corrosion, and a well-designed housing is important for durability and protection of internal components. The diaphragm itself can be made from materials like butyl rubber, neoprene, or Viton, each offering different resistance to chemicals and temperature. Steriflow Valve offers manual or air actuated forged 2-way sanitary valves, providing flexibility for various applications.
