NAF-Setball ball sector valves DN -0, PN 0-, ANSI Class 0-0 Fk 4.()GB 03.0 Primary characteristics NAF-Setball is a ball sector valve with metal-to-metal or metal-to-ptfe seating. The NAF-Setball combines the best control characteristics of the ball valve and the butterfly valve. It can be used both as a control valve and as a shutoff valve. It is available as standard in stainless steel. It is also available in other materials, such as, CG8M, Titanium, etc. Contact NAF for more information The valve has: a one-piece, leak-proof stainless steel body, with face-to-face lengths in acc. with IEC standards a ball sector with top and bottom bearings for low operating torque, so that low-torque actuators can be used a V-shaped sector that provides accurate control over a wide range, even at low flow rates and if used for viscous media with high concentrations of solid particles a spherical area of the ball sector which, with PTFE-seat gives tight closing. The Stellite seat ring, ensures excellent tightness at all differential pressures. The maximum leakage in the direction of flow is less than x 0-6 of the Kv value in this case. Metaloplast bearings or hard chromium plated stem, direct mounted in the body. O-ring or graphite packing for the stem gland The standard Stellite seat can easily be converted to PTFE after turning the ball sector by degrees, without the need to dismantle the valve. NAF standard for mounting the actuator, which simplifies installation and results in a compact valve/actuator unit CE-marked according to Pressure Equipment Directive (PED 97/23/EG) module H, category III. For module H, category IV contact NAF Applications NAF-Setball can be used both as a control valve and as a shut-off valve, in a wide variety of applications and in different operating modes.the valve represents a concrete result of our product philosophy which is focused on functionality, high quality and low life cycle costs, and is based on concentrating our range to a limited number of valve types, but all of them suitable for a wide variety of applications. The excellent control characteristics of NAF-Setball are particularly beneficial under severe control conditions, in difficult media and under demanding pressure conditions in the process industry, such as: if the media contains solid particles if a wide control range is required in control applications involving high pressure drops if cavitation occurs corrosive applications Technical specification Material: Stainless steel Size range: DN -0 Pressure ratings: PN 0, 6,, ANSI Class 0 and 0 Max. differential pressures: valve closed bar DN -0 control service bar DN - bar DN 00-0 0 bar DN 0-0 8 bar DN 0-0 See also page 2 Face-to-face lengths: As per IEC 34-3-2 Installation methods: Wafer type (DN -0) Flanged (DN -0) Temperature range: - - 0 C Test pressure:. x PN with valve open IEC 34-4 Class IV-S with valve closed Sealing class: PTFE-seat ISO 8-2 Rate A DIN 32 BN Leckrate Metal seat IEC 34-4 Class IV-S.
Working pressure, differential pressure and temperature The maximum working pressure and temperature in the body depends on pressure class according to respectively flange standard. Max. differential pressure, valve closed, depends on temperature as shown in the diagram and is valid for all sizes. Max. differential pressure for control service and sizes DN 00-0 depends on size and temperature as shown in the diagram. Valves with PTFE-seat is further limited as shown in the diagram.

Valve positioner Pneumatic and electro-pneumatic valve positioner, see data sheet Fk4.82. Intelligent valve positioner, see data sheet Fk4.8. Intelligent On/Off controler, see data sheet Fk4.86. Solenoid valves See data sheet Fk79.7. Electrical position indication See data sheet Fk79.0. Terminal box The actuator can be equipped with a junction box (part No. 349 9) of cast aluminium containing terminal blocks for connecting the solenoid valve and position sensors. Other versions - Stem seal in other materials For temperatures up to 0 C the standard O-rings item 3 and as per Fk 4.GB can be replaced by PFM, Isolast. For higher temperatures, contact NAF. Product code K - Degreased version for oxygen Before assembly, all valve parts are degreased in trichlorethylene vapour. The valve is assembled and packaged so that no oil or grease will enter the valve. Product code D - Stem sealing for vacuum For vacuum the stem sealing O-rings kit is turned to be tight against the pressure from the outside. For applications with alternating vacuum/overpressure is the overpressure limited to 2 bar. Product code V - Internal O-rings for sealing the stem from the medium For media containing small, hard solid particles (such as those in flue gases, powders, granulates), and media which can crystallize in narrow slits. Those media can penetrate into the stem seal and give rise to increased actuating torque or increased ware. O-ring seals are arranged between the body and the body side of stem.
