Hydraulic valves

RAF

RAF 
In 1993 Raphael has launched RAF - a new concept of diaphragm hydraulic control valve consisting of three basic parts: body, cover and diaphragm, each one is made of durable materials.
 
The inner flow passages are streamlined and coated with low-friction materials.
This provides quiet flow in both directions, low head-loss and minimal wear.
 
RAF valves operate with a patented reinforced diaphragm, which eliminates the need for a retaining metal spring. The special elastic design enables gradual and precise opening and closing of the valves.
By eliminating a metal spring, the RAF is virtually maitenance free.
  
Diameter: DN25 - DN350
Standard: DIN/ANSI/BS
