1401 Type Pneumatic Membrane Angle Single-Seat Regulator

1401 type pneumatic membrane angle single-seat regulator adopts top-guided structure and is equipped with

multi-spring membrane actuator. It has the advantages of compact structure, light weight, sensitive action, low

pressure drop loss, large valve capacity, accurate flow characteristics, easy disassembly and installation. Widely

used for precise control of gases, liquids, vapors and other media, process parameters such as pressure, flow,

temperature and liquid level are maintained at a given value. Angle valve are specially used for medium with high

viscosity, easy to crystallize, containing suspended particles, 90 ° bends, because the angle single-seat valve body

has no dead angle, easy to blow, so it is especially used in the food industry.

This series of products have various types such as standard type, regulating cut-off type, bellows sealed type,

jacketed insulation type, low temperature type, high temperature heat dissipation type etc.
