Page 3: Intended Use
1. INTENDED USE Product Number 4493, 4493SA eccentric butterfly valves are intended for potable water supply systems, sanitary sewage systems and (if approved by the manufacturer) industrial media systems. Each valve can be installed in overground and underground pipelines as an integral in-line part of the piping. The butterfly valves are used to shut off and regulate the flow of the medium using a part-turn gearbox, electric actuator or a multi-turn actuator unit with a part-turn gearbox. - Page 4 Series 14. • Butterfly valves with a soft seal (4493, 4493SQ, 4493SA) in diameters DN200 ÷ DN2000 have a double- seated cover (disk). The valve pivot shafts are held by the necks, mounted on additional bearing sleeves. The pivot shafts are sealed by the packing gland assembly, comprising an arrangement of o-rings. The butterfly valve is closed with a cast iron disc fitted with an elastomer seal.
- Page 5 The valve without a gearbox forms an assembly that can be adapted to various control devices (gearboxes, actuators). To ensure proper leak-tightness of the valve, an operator can only be installed by an authorized service of Fabryka Armatur JAFAR. The operator must ensure a stable closure actuation angle within: ➢...

5.1. GENERAL REQUIREMENTS Flanged butterfly valves: TYPE 4493, TYPE 4493SQ and TYPE 4493SA can be installed in underground or overground pipelines on horizontal or vertical installations. The listed products are suitable for joining with the flanged ends of pipelines with the size equal to that of the valve flanges. The valves are bi-directional tight. The valves are to be installed in the pipeline so that the flow direction of the medium is in accordance with the flow direction indicated on the body. - Page 9 - Fig. 9. The permissible deviation from the horizontal location of the shafts in relation to the horizontal axis of the pipeline is from 2 to 5 degrees. Fig. 9. Orientation of the valve closure pivot shaft relative to the piping plane shown for Product Number 4493 DN500 a) Vertical piping b) Horizontal pipeline...
- Page 10 Fig.10 The movement of the valve flap in the standard version The above Fig.10 shows the standard version of eccentric butterfly valves with the JFR GRAY gearbox. The standard movement that opens the flap is clockwise. In contrast, the permanently marked arrow on the valve flap pivots shows the movement that closes the flap (counter clockwise).

Start from the bolt holes near the valve pivot shaft. The tightening torque of the bolt nuts is specified in the standard PN-63/M-82056. During mounting, it is necessary to consider making bases or supports for butterfly valves, which must be adapted to the size and weight of the valve in order to avoid transferring the load into the pipeline. - Page 12 The fittings may be used in chambers (tanks) only after prior agreement between the customer and Fabryka Armatur Jafar. - special realization. As stated in point 2, the control is carried out by a T- key, stands or an electromechanical actuators including fixed casing Product Number 9025. When mounted in the ground, the manufacturer recommends the use of a street box Product Number 9501 mounted on a base plate Product Number 9521 or an equivalent product ensuring rigid foundation of the box.
