Pneumatic actuator accessories to Namur
New pneumatic actuator accessories from Ultraflo direct mount and comply with Namur recommendations (VDI/VDE 3845) as standard: these include 4 and 3-way solenoid valves and a valve status monitor
The 410 model, a wafer style body, is available in sizes 24" - 36".
The 412 model, a double flanged style body, is available in sizes 24" - 48".
Valve bodies are offered in cast and ductile iron, cast steel and stainless steel and comply with ASME/ANSI 125/150 flange drilling standards.
412 models may be bolted to allow downstream flange removal or cross-bolted for high resistance to line media stress.
The Ultraflo resilient seat is the heart of all 410/412 Series valves.
The seat design offers lower torque and complete isolation of the line media from the valve body.
All 400 Series seats include a flange seal moulded into the seat face providing a positive seal with all popular flanges.
Discs are available in a variety of materials and custom coatings.
The one-piece heavy duty, high strength stem includes industry standard connections for actuator mounting.
The thrust bearing eliminates disc displacement due to stem and disc weight.
All body sizes have a CNC machined top plate with standardised drilling for total actuator and operator interchangeability.
The V-type packing design is self-adjusting with bi-directional sealing to prevent external substances from entering the stem bore.
412 models feature externally adjustable packing, which is ideal for vacuum applications.
Designed to recognised industry standards, the stem connection provides a secure connection with most actuators, eliminating the need for brackets.
All Ultraflo valves are tested to 110% of pressure rating for bubble tight shut off before shipment.
