With the addition of a diaphragm top (model C-0152), the valve may be held closed by 35 PSI (2.4 Bar) air pressure. This is commonly used to eliminate or delay high-pressure “kick-in” until a later part of the cycle. With no air pressure on the diaphragm, the model C-0152 works like the standard B-0511 valve.
Renewable trim is made of hardened stainless steel.
Proven to be very resistant to the effects of corrosion, wear, and wire drawing for longer service life.
Piston is fully-guided.
Results in ideal alignment of the seat and disc.
