Product catalog summary
Overview of Diaphragm Valves
Diaphragm valves are designed for high resistance to corrosion and abrasion, ensuring complete watertightness and minimal maintenance costs. The sealing mechanism involves a membrane pressed by a specially designed compressor against a curved seating surface. Despite having a vertical seat, these valves experience minimal pressure loss due to the body design and membrane curvature.

Construction Materials
  • Body Materials: Options include cast iron, cast iron covered with ebonite, rubber, neoprene, halar, and stainless steel.
  • Membrane Materials: Available in natural rubber, neoprene, EPDM, butyl, perbuna, hypalon, viton, and teflon.

Working Conditions
  • For sizes 1/2" to 3": PN-10
  • For sizes 4" to 6": PN-6
  • For sizes 8" to 12": PN-4

Dimensions and Standards
The document provides a detailed dimensions panel according to DIN standards, listing sizes (DN), dimensions (A, B, C), number of holes (N*), and flange sizes (F).

Component Materials
The valve components are made from various materials, including:
  • Body: Inox CF8M or Iron 6625
  • Diaphragm: As per demand
  • Disc: Iron 6625
  • Nut: Bronze
  • Cover: Iron 6625
  • Handwheel: Iron 6625
Other materials and dimensions are available upon request.

VALVULA DE MEMBRANA-1

VALVULA DE MEMBRANA DIAPHRAGMA VALVE NORMAS DIN DENOMINACIÓN / PART SEGÚN DEMANDA / BY REQUEST PISON / DISC TAPA / COVER MEMBRANA / DIAPHRAGM CUERPO / BODY VOLANTE / HANDWHEEL Otros materiales / dimensiones consultar Others materials / dimensions on request Las válvulas de mémbrana, presentan en términos de resistencia a la corrosión - abrasión, completa estanqueidad y mínimo coste de mantenimiento. El cierre lo efectúa una membrana contra una superficie de asiento curva, empujada por un compresor de forma especial. Aunque es de asiento vertical tiene muy poca pérdida de carga por la forma del cuerpo y la curvatura de la membrana. Amplia selección en los materiales del cuerpo, tanto revestidos como sin revestir, así como diversas calidades de membranas hacen que puedan cumplir un amplio campo de trabajo aún en las condiciones más difíciles. MATERIALES DE CONSTRUCCION CUERPO: Hierro Fundido; Hierro Fundido recubierto de ebonita; Goma; Neopreno; Halar; Acero inoxidable. MEMBRANA: Caucho Natural; Neopreno; EPDM; Butilo; Perbuna; Hypalón; Vitón y Teflón. Advantajes of diaphragm valves are: resisting to corrosion and abrasion, absoluta watertigh and litle cost for maintenance. Seal is done by a membrane that´s pressed by a special pattern embólus against a curve surface seat. Althoug it´s a vertical seat valves, the lost of pressure is minimum in due to the pattern of body and the membrane´s bend. A lot of kinds of materials for the body covered or not, and the differents qualitys of membranes are the reason for these valves can work even in the most difficults conditions. MATERIALS: BODY: Cast Iron, cast iron covered with ebonite; rubber, Neopreno, halar stainless steel. MEMBRANES: Natural rubber, Neopreno, EPDM, Butilo, Perbuna, Hypalon, Viton and Teflon.
