Rolling Diaphragm
Integrated Accessory Attachment
Greatly reduces diaphragm wear

• Eliminates external tubing reduced compared to Stretching diaphragm

Single Bonnet/Yoke Design

Self-adjusting PTFE V-ring Packing Actuator removal without the
need to open the valve Bonnet
• Maintenance-free design and body of the valve always
• Low friction have same metallurgy Fewer
• Roller burnished stem reduces friction ex- components results in a lower
ternal leakage, and maximizes packing life profile valve
beyond what basic polishing can offer from
competitors.
• Double wall design
• Small valve travel results in a long bellows Low Lying Guide Bushing
life Ensures precise plug alignment
• Modular design allows for the addition or for our stem guided
removal of assembly bellows in the field
• Straight Thread Seat Design No cage,
gaskets or seals required trim Few-
