K53 Series
The K53 series incorporates the critical features of the K52 series and improves performance. A double O-ring design on the shaft eliminates the possibility of contamination of the process and control fluids. K53 series valves have a high lift poppet design for flow capabilities at least 20% greater than the K52 series.

VAV Series
The VAV series is similar to the V42 series and share cast iron bodies and caps. The VAV series has been enhanced to allow a longer cycle life by a seating disk material of 90 durometer and Aflas dynamic O-rings. Valves of 2-inch pipe size and larger offer stainless steel diaphragm plates for added strength, and double O-rings on the shaft for better stability.
