1 WTR SRIS QULITY Y TRITION sil mla water meter valves THNIL SHT 05/2017 IP09020 SOP SRVI ONITIONS SIL ML series are metallic ball valves manually operated that, due to their design are intended to be used in: - rinking water supplies. - Home feed applications. In general, all those applications that require a valve capable of shutting off the liquid flow, assuring leak tightness and fulfill all the following service conditions. SIL ML are quarter turn valves. Nominal pressure: Test pressure: Temperature range: Fluid: 16 bar 25 bar old water rinking water PG. 1/8

4 QULITY Y TRITION MIN ONSTRUTIV FTURS OY N LTRL Main body and lateral made in uropean brass W617 by means of hot stamping process. oth process and the material confer the following advantages versus casting valves. - Pores and bumpy texture absence. - Surfaces with better finished. - Higher mechanical endurance against high pressures. O-rings STS Made in PTF, assuring internal and external leak tightness due to its perfect fit on metallic surfaces. INTRNL leak tightness Internal leak tightness is assured in both directions by the PTF seats that press against the spherical closure. This system can not be dismantled, avoiding improper manipulations. XTRNL leak tightness xternal leak tightness is achieved by the mean of a pair of NR O-rings. These avoid every leak and moreover are allowed to be in contact with drinking water. PTF Seat IMNSIONS SIL Straight F-LN Size 1/2 F x 3/4 LN G1/ /4 F x 3/4 LN PG. 4/8

INSTLTION N SSMLY The installation of valves must be done with the right tool, mostly with a spanner. Hold the valve from the end of the connection, never from the central part or the neck of the valve in order to avoid internal components deformation, the valve could be damaged inevitably. The maximum lifespan of the valve is obtained with the spherical closure in full open or closed position, it is recommended to not operate in intermediate positions for long time periods. Valves should be maneuvered every 3 months. This frequency should be increased for waters with French hardness over 50º.
