OKM 54 Series Butterfly A leading-edge butterfly valve for high-performance flow control:-

• self-sealing mechanism ensures tight shutoff
• double eccentric disc ensures longer service life, low seating torque and leak-tight shutoff

The OKM 616 Butterfly Valve features a patented “Touch” seat design that works together with an S-shaped disc to provide smooth, dependable bubble-tight shutoff and and extended service. The design accommodates working pressure up to 16 bar. (232 psi) and flanges comply with ISO, ANSI, BS, AS, DIN and JIS.

OKM 616 Butterfly Valves - The S-Shaped disc enhances the CV rating and promotes flow control without turbulence. The valve can be operated at the lowest possible operating torque with bubble-tight  shutoff at the maximum operating pressure.

OKM 612X & 615X Butterfly Valves - A product that offers merits through it performance and economical feature. It also reduces torque requirement through its unique OKM seat structure which make it possible to have longer seat ring life.Low torque & longer life due to its unique new OKM soft touch seat: A newly developed soft touch seat that presses in with a smooth angle when the disc touches at the rubber seat.

The OKM 620 Butterfly Valve features a patented "Touch" seat design that works together with an S-shaped disc to provide smooth, dependable bubble-tight shutoff and an extended service. The design accomodates working pressure up to 20 bar. (290 psi) and flanges comply with ISO. ANSI, BS, AS, DIN and JIS.

Astam Super Check Valve preventsfrom Water Hammer. Reaction oftorsion spring installed inner valvemakes plate rapidly close prior tothe start of revere flow of fluid dueto the stop of power, thus preventsline, pump and other piping facilitiesfrom the damage and trouble due tothe Water Hammer.

The super check valve consists of two plates hinged on a single pin. The load is carried by two plates supported at the center by a single beam the the cylindrical valve body. The curved portion of the plates are supported by a flat shoulder in the valve body. The torsion spring actuatesthe plates for positive closure before the reverse flow can occure in most applications. 

The valve is short Face-to-Face, easy to install in a narrow space. Compact figure andlight weight compared with the conventional Swing Check Valve, and simple design isin the true sense of easy to maintain due to small number of component part inAstam’s valve.
