VASCO – VAriable Speed COntroller is a purpose-built family of variable frequency drives, designed to control and protect pumping systems based on changing pump speed.
From water supply for domestic, irrigation, commercial and industrial applications, to heating and air conditioning, from filtering to pressure washing, the range perfectly fits any new or existing application ensuring:
Unique “reverse flow” design permits equal pressure distribution on both sides of the diaphragm, regardless of line pressure, providing zero stress to prevent “stretching,” a common cause of valve failure
Diaphragm’s self cleaning ports constantly flex, inhibiting sand and silt from blocking valve action
Molded shock cone for smooth operation and reduction of water hammer
Easy-to-use internal manual bleed lever; bleeds valve downstream; has positive stops for open and closed positions
Marine-grade S20P solenoid with stainless steel actuator
High-strength glass-filled nylon body and cover with 1⁄4″ stainless steel cover bolts and mating brass body inserts
Non-rising flow control stem throttles valve from full open to closed position on flow control models
