Air Operated 2 Way FIP VKD ABS Ball Valve

Transcription

1 Type: PA3112F Actuator fitted via EasyFit-F mounting kit Pneumatic Actuator features: Rack and pinion construction Hard anodised extruded aluminium body Epoxy coated cast aluminium end caps Pre-tensioned spring sets, no special tools needed to change Low friction sliding parts Factory lubricated for life (high temperature grease available) ATEX approved for use in Zone 1 EExd applications Local visual position indicator ISO5211, VDI-VDE3845 & Namur compliant Applications: ABS (Acrylonitrile butadiene styrene) is an extremely robust thermoplastic pipework system used by many industries in systems for food and beverage production, sewerage and water treatment etc. ABS is extremely resistant to impact with good resistance to chemicals, and is non-toxic. ABS has good chemical resistance with high impact strength, and has good resistance to most diluted inorganic acids, salts, animal fats and oils, and organic acids. It is not resistant to organic solvents, alcohol, petrol, acetic acid or vegetable oils. Ball valve information: The FIP VKD is a true union ball valve particularly suited to industrial applications where high performance and reliability in service are primary considerations. The patented Seat Stop system assures longevity of the seals particularly in cases where thermal expansion is expected. It is possible to micro-adjust the seats. The new patented Dual Block system allows proper union nut tightening without any risk of unscrewing. Automation is made quick and easy when using the J+J designed and manufactured EasyFit-F mounting kit.

How this air operated 1/4 turn valve works (on-off): Within the cylindrical bore of the actuator are 2 opposing aluminium pistons, each with an integrally cast rack, which is driven by a bearing supported nickel plated steel pinion. The housing has air ports drilled to allow compressed air supplied via the air connection ports to flow either in to the cavity between the pistons to drive them apart, which compresses springs contained between the top of the piston and the end caps, and, via the rack & pinion system, rotates the actuator s output drive shaft. Releasing the compressed air releases the stored spring energy which reverses the direction of rotation of the output shaft as they decompress. Final open and closed positions are set with adjustable mechanical stops. Standard: Hard anodized extruded aluminium body, with epoxy coated aluminium end caps.

3 Method of assembly and accessories for position feedback, position monitoring and position control Safe area switchbox fitted Safety Notice: Ensure positioner, switchbox and/ or solenoid are compatible with the intended installation area - is it a safe area, or a hazardous area? If hazardous, which Zone? We can supply either. Call to check if unsure. Positioner: Sets the degree of opening of the actuator (and therefore valve) proportional to a control input signal. This signal can be either 4-20mA, or 0-15psi. Switchbox: Internal switches, activated by cams or similar, driven by the actuator s pinion, make a circuit at end of travel (ie: full open, or full closed) to provide remote end of travel confirmation. Also has local visual position indicator Solenoid: Provides electrical control of the pneumatic actuator. Air remains energised permanently, the solenoid valve switches to control the opening and closing of the actuator. Safe area Namur solenoid fitted. Safe area pilot solenoid and switchbox fitted. The solenoid can be pre-wired to the switch-box.
