The HD MEDIUM VELOCITY WATER SPRAY Nozzles EACH K-FACTOR. are open type (non-automatic) nozzles, designed K FACTOR MV-A/MV-B MV-AS/MV-BS for directional SPRAY application in fixed fire & MV-E protection system. Metric (US) Metric (US). MEDIUM VELOCITY WATER SPRAY NOZZLE has an K-18 ( ) K-18 ( ). external deflector, which discharges WATER in a K-22 ( ) K-22 ( ). directional cone shaped pattern of small droplet size. K-26 ( ) K-26 ( ) The WATER is uniformly distributed over the surface to K-30 ( ) K-30 ( ).

2 Be protected. K-35 ( ) K-35 ( ). K-41 ( ) K-41 ( ) MV Nozzles are effectively designed to apply WATER K-51 ( ) to exposed vertical, horizontal, curved and irregular K-64 ( ) shaped surfaces to allow cooling to prevent K-79 ( ) excessive absorption of heat from external fire K-91 ( ) and avoid structural damage or spread of fire. In some K-102 ( ) application nozzles may be installed to control or extinguish the fire depending on WATER design density FINISH MV-A & MV-AS. as per applicable codes. The NOZZLE is used in deluge Natural Brass finish, WATER SPRAY system for special hazard fire protection Nickel-Chrome plated, application. Electroless Nickel plated, Epoxy powder coated. As the design and intent of specific WATER SPRAY system MV-B, MV-BS & MV-E may vary considerably, MV NOZZLE is made available in Natural finish several combinations of orifice sizes (K-factors) and SPRAY angles. APPROVALS UL Listed, FM Approved &. LRS-Lloyd's Register Approved The minimum desirable pressure to achieve a Blow-off Plug- FM Approved reasonable SPRAY pattern is The WATER For Approval data refer Table-II distribution pattern as shown in the graph in following pages is at an average pressure of The ORDERING Specify K-Factor, SPRAY angle, change in pressure between to INFORMATION finish, model and end does not affect considerable change in SPRAY angle.

3 Connection The SPRAY pattern shown is with indoor application. System designer must consider wind VELOCITY while designing the system for outdoor application. Field obstruction if any affecting the SPRAY pattern of the NOZZLE must also be considered. The NOZZLE may be oriented to any position as deemed necessary to cover the hazard. OCTOBER, 2020 PAGE 1 OF 8 HD 108. HD FIRE PROTECT. PVT. LTD. The Blow-off plugs can be used to prevent the The nozzles must be hand tightened into the depositing of foreign materials in the WATER way of the fitting. After hand tightening use NOZZLE Wrench- nozzles, which could interfere with discharge of the NW-M for wrench tightening in to NOZZLE SPRAY NOZZLE . Blow-off plugs are optional and are FM fittings. Excessive tightening torque may result Approved. Blow-off Plugs have identification mark with into serious damage to NOZZLE arms and the respect to K factor. For example, Blow off plug for deflector, which may affect SPRAY pattern of the NOZZLE having K-factor 22 will have identification mark NOZZLE and its performance.

4 Of 22. Minimum operatiiong pressure for NOZZLE having Blow-off plug is (20 PSI). It is recommended that WATER SPRAY system be inspected regularly by authorised technical The main pipeline strainer as per NFPA-15 is required personnel. for system utilizing NOZZLE orifice diameter less than (3/8 inch), NOZZLE having K-factor 41 The NOZZLE must be checked for atmospheric effects, and less, and also for the system WATER likely to external and internal obstruction, blockage if any. contain obstructive materials. The system must be operated with optimum WATER flow at least twice in a year or as per the provisions INSTALLATION & MAINTENANCE of NFPA or local authority having jurisdiction. The SPRAY NOZZLE must be handled with due care. It is recommended to design WATER SPRAY system as For best results, the storage as well as any further per guidelines of NFPA15 and/or AHJ. shipment shall be made in original packing only. The owner is solely responsible for maintaining the NOZZLE which is visibly damaged should not be installed.
