Butterfly valves Val-Matic’s American-BFV ® butterfly valves for shut-off service in water systems are designed to provide long life, low headloss and trouble-free performance. Features such as standard epoxy interior, continuous uninterrupted seating, and the Tri-Loc™ seat retention system allow for field adjustment/replacement without the need for special tools or epoxies. American-BFV butterfly valves

Val-Matic’s American-BFV butterfly valve

are available in 150B and 250B AWWA classes with flanged end connections in sizes 3" to 144", and mechanical joint end connections in 4" to 48". Wafer style butterfly valves are designed with ANSI 125 flanges or ISO PN10 and PN16 flanges in sizes 4" to 24". The valves fully comply with AWWA C504 and C516, are certified NSF/ANSI 61 for drinking water, and are NSF/ANSI 372 certified lead-free.

Connecting joints also support cable protection tubing

from the corrugated tube while also protecting the tube against an ingress of foreign matter that might accelerate wear. With the launch of the new TKKSB- 48 type, all common nominal diameters from 23 to 70mm are now available. All sizes can be ordered with different standard drilled-hole patterns, as well as in a blank version.

of 70mm, matching the dimensions of conventional industrial robots. The new parts complement Reiku’s extensive range of cable protection systems for use in OEM applications and customers’ spare part stocks. The manufacturer produces these connecting joints from a specially modified, cadmium-free and halogen-free flame resistant polyamide 6 to ensure an optimum protection of conductors and cables. Reiku has also rounded out its portfolio of cable stars, which provide pull-relief for the cable and hose bundles exiting

Reiku has introduced connecting joints for corrugated cable protection tubing measuring 23mm and 36mm in nominal diameter. With these items, the manufacturer caters to a growing trend for small-sized industrial robots in automation technology. A joint of this type typically connects two corrugated tubes of identical nominal width. In this case, both tubes can rotate through 360° in their seat so that no torsion moment will be transmitted. Instead of connecting one tube to another, the joint may also link a tube to a cable star – a device employed to secure cables and to seal off the tube end. Alternatively, one side of the joint is configurable as a ball trumpet having rounded edges to protect against abrasion. The two halves of the split assembly are held in gripping clamps whose ball-shaped seat permits up to ±11º angular offset. The clamps can be attached to the robot by means of rotary bases allowing the system a 360° orbital rotation. The total degrees of freedom obtained and the low mounting height of Reiku’s joint systems give the robot a wide action range, even with high-speed movements, and allows it to be used flexibly even in narrow working spaces. At the same time, mechanical loads in the cable protection system are significantly reduced in this manner, supporting an extended system lifetime.
