Series 700 actuators are pneumatic diaphragm operators that offer spring return in either direct or reverse acting styles, offering fail-open and fail-closed modes respectively.
The actuators may be fitted with a variety of springs in order to overcome the wide range of forces that may exist on a valve plug. An adjusting mechanism is incorporated into the actuator design to allow for adjustment of the spring pre-compression.
The series 700 actuator is available in 60, 100 and 160 square inches of effective diaphragm area and may accommodate up to five inches of travel.
Design Features: DeZURIK diaphragm actuators are designed specifically for use on quarter-turn valves. They feature all steel, cast iron and stainless steel construction for corrosion resistance in caustic environments. The actuators are designed for on-off or modulating service in either a fail-open or fail-closed mode. Action can be easily changed in the field with no additional parts required. The spring cartridge is caged at the factory for increased safety. The output shaft is supported at the top and bottom with bronze bearings that absorb side thrust and insure smooth, efficient, and accurate throttling control.
1. 4.2mm square: 4.2¡Á4.2¡Á23.1mm*1
An innovative and groundbreaking ultra-small solenoid valve - can be mounted in the smallest of spaces, minimizing the manifold size and shortening the length of flow paths.
*1 Dimensions for FV-2-MFG, not including wire connections
2. Diaphragm valve
Excellent chemical resistance ¨C PEEK and Perfluorelastomer are used for wetted materials (materials can be changed according to your requirements).
3. Internal volume only 1.1¦Ìl*2
Through pursuing miniaturization to the uttermost limits, internal volume is now only 1.1¦Ìl ¨C contributes to reductions in reagent and sample quantities and improvements in analysis accuracy.
*2£ºvalue for FV-2-MFGA(B). FV-2-N1G: 4.3¦Ìl¡¢FV-2-MFG: 1.5¦Ìl
This small valve enables you to reduce not only the installation space but also internal pipe length of your manifold by making it possible to mount at 6mm intervals.
- Capacity for Bilateral Connection
Easy to make manifolds
- Small Internal Volume
Only 10 micro liters (each port)
- Excellent Chemical Resistance
PEEK molded body and Perfluoroelastomer diaphragm
Remote Control Valve:
Hayward's Pneumatically Actuated Diaphragm Valves are designed for the reliable, remote control of liquids in piping systems. They are suitable for both clean and slurry type fluids at pressures up to 150 PSI.
Position Indicator:
You never have to guess if a Hayward Diaphragm Valve is in the open or closed position. A visual position indicator comes standard with every valve.
Powerful Actuator:
The actuator used to operate the valve, while lightweight and compact, is still powerful enough to open and close the valve at all internal pressures up to the full rated pressure of the valve,150 PSI.
No Corrosion Problems:
Hayward's Diaphragm Valves stand up to the most aggressive fluids and they will never rust, corrode or contaminate the process fluid. Even the actuator housing is plastic and requires no failure prone coating or painting.
Modular Options:
Several modular design options are available. This concept is very cost effective because the actuator can be configured exactly for a specific application using only the options required. You never have to pay for options you do not need.
Additional to the manual iris diaphragms motorized versions are available. These have the advantage to drive the iris diaphragms remote controlled, for example in inaccessible places or in closed devices. The motorised iris diaphragms are compatible to the System Kit SYS 65, this means that they have an optical height of 32.5 mm. The motorisation is available in two different types, either with 2-phase step motor with preloaded gear or with DC servomotor with encoder and preloaded gear. The iris diaphragms have two reference/limit switches to indicate the end positions (iris diaphragm open or closed).
Totally closing iris diaphragms consit of two lamella sets with 2.8 mm distance.
- for use with SYS 65
- aperture 0 up to 35 mm
- black anodized aluminium alloy
- mountable onto slide
- contact-free and high-precision limit switches (Hall sensors)
- with 2-phase step motors with gear or DC servomotors with encoder and gear
This 1-1/4" bore diaphragm cylinder is designed for a clamping application with minimal friction losses. Its short overall height allows the cylinder to fit into a tight space with minimal friction.
Stroke length: .12".
Output force will be approximately 15% less than theoretical when units are not extended full stroke.
Cylinders should not be operated without a part being clamped (extension should be limited by customer to maximize life).
