QUADRA-POWR X SPRING-DIAPHRAGM ROTARY ACTUATORS

Transcription

1 QUR-POWR X SPRING-IPHRGM RORY CUORS Exclusively developed for quarter-turn valve service, Quadra-PowrX -diaphragm actuators provide safe and reliable operation even when minimal supply pressures are available. Yet they are capable of operating at pressures as high as 7 bar (00 psi). hese units can be operated by, gas, water, oil, or other supply media compatible with the ductile iron/carbon steel casing of the actuator and the una-n diaphragm reinforced with polyamide fabric. Quadra-PowrX torque outputs range from to 79 Nm ( to 87 ft lbs), depending on actuator selection and available supply pressure. EURES djustable travel stops llow the actuator to be adjusted in both fully open as well as fully closed position. High cycle-life design Rolling diaphragm design, along with new one-piece diaphragm retainer and UHMW Polyethlene bearing, assures extremely long cycle-life. Low-friction operation provides exceptionally smooth actuation. Wide supply pressure range Unlike most -diaphragm actuators, the Quadra- PowrX can be operated up to 7 bar (00 psi). s are available with four different ranges for.,.8,. &. bar (0 psi, 0 psi, 0 psi, and 80 psi) supply pressures. Low friction bearings cetal-lined stainless steel backed bearings offer a low coefficient of friction that allows virtually all of the available torque to be delivered directly to the output shaft. Keeps the actuator size as small as possible while delivering hundreds of thousands of smooth cycles. UHMW Polyethylene bearing fully guides the diaphragm retainer through stroke of actuator, ensuring smooth operation and low friction. Corrosion resistant Zinc phosphate epoxy based primer coat and UV resistant polyurethane top coat provide durability and protection in corrosive atmospheres. ll stainless steel external fasteners. Wet conditions kit available for extreme environments. Low maintenance Lubricated at the factory. No further lubrication is required. Easily fitted with a variety of accessories Wide range of optional accessories and control devices, which include direct-mount sandwich manual overrides, limit switches, position indicators, two-stage flow controllers, positioning and programmable cycling controllers, are available to satisfy virtually all automatic valve requirements. Completely field reversible ail-open or fail-close operation can be quickly changed in the field by simply inverting the actuator. op and bottom mounting pads are identical. Springs are pre-loaded in a self-contained cartridge for safer handling and easier maintenance. /08

5 QUR-POWR X SPRING-IPHRGM RORY CUORS CUOR CCESSORIES N CONROLS CONSRUCION OPIONS 00 % adjustable stop option - ir stroke only Mechanical lockout option o comply with the intent of OSH requirements for locking -driven actuators in the -driven position, every Quadra-Powr actuator can have the mechanical lockout option added to it. esign of the output shaft allows for locking the actuator in the -fail position. s equipped with this option have a special lockout screw and a tamperproof cover attached to the housing of the actuator with a stainless steel wire. he lockout parts are readily available to permanently lock the actuator in place and padlock the locking device to prevent unwanted operation. When limiting the rotation of the stroke of a Quadra-Powr actuator, a 00 % adjustable stop option can be added. In the -to-close mode this option limits the opening stroke only; in the -toopen mode it limits the closing stroke only. he stop screw for this option is located in the housing end of the actuator. Wet conditions (tropicalization) kit ll standard QPX actuators are shipped with all open mounting and accessory holes filled with fasteners. his reduces the possibility of standing water to enter into the driver housing. ut in extremely moist environments, water can still potentially make its way inside the unit. In fact, all return actuators are subject to this. Every time a QPX strokes inside the actuator (on the non-pressure side of the diaphragm) is pushed outside via the breather. his is due to the decreasing volume and differential pressures that are present. In contrast, when the actuator returns on the stroke the exact opposite happens- must be pulled inside the actuator, and in a humid environment, taking along moisture with it. o block off all openings in the actuator would stop the operation, as this breathing needs to happen for a -return diaphragm actuator to function. he only realistic way to eliminate all moisture from getting inside the actuator is to regulate the that is being transferred in and out of the actuator. his can bedone with an accessory called the ropicalization kit. his accessory kit takes exhaust from the solenoid valve or positioner (clean dry ) and re-directs it into the housing in place of the breather fitting. his is dumped inside the housing during the stroke, thus keeping a positive pressure in the housing, and keeping out atmospheric (and moisture). his kit should be considered in any application where excessive moisture exists. usible plug fusible plug option is available for all Quadra-PowrX actuators to allow for automatic closing or opening of the valve in the event of a fire or excessive environmental temperature. he standard plug is designed to melt when the temperature reaches an approximate level of (7 C). his releases the from the diaphragm case and rotates the valve to its fail-closed or fail-open position.o order a fusible plug kit specify LK.
