Valves – Choosing The Right Strategy
Systems – Straight figures are machined from bar stock. ISO 6149 uses metric parallel threads and male end includes a unique identification groove. Parker Hannifin has some very nice resources for hydraulic fittings, including literature the correct fitting installation methods as well as the Parker FittingFinder mobile application for on-the-go help for deciding on the best fittings.
The 3 feminine connectors have actually right threads and a sealing area. This -Ring Face Seal connection offers a remarkable drip resistance and it’s also appropriate applications which can be around 6000 psi. The male has a 30° seat and a straight feminine half has a 300 seat and a straight connection resembles 37° Flare.
Generally speaking, 60° cone fittings are for applications with pressures ranging from 1,100 to 5,000 psi. The SAE female has directly threads and a 45° flare chair. But metal-to-metal seals aren’t because dependable as elastomeric seals found, including, on -ring seal fittings. Its distinguishing characteristic is metric parallel threads in the place of BSPP threads.
NSPM connections find numerous applications in fluid power systems. Strenuous tests holds away within our technical laboratory in Casalgrasso (CN) have actually clarified, beyond any question, the reliability associated KP-LOK O-Ring Face Seal (ORFS) Fittings with sealing of this range of oleo-dynamic fittings. Tube fixtures are customarily ranked with a 4:1 design factor for normal running conditions and moderate mechanical and hydraulic shocks.
The NPTF male has tapered threads and a 30° inverted seat. The male has straight threads and an -Ring. It’s also easy for some tapered males to thread into certain parallel female threads, but there are lots of factors involved so caution ought to be taken. The female end associated with the inverted flare has a 420 chair that provides a sealing area.
Therefore, there is certainly a full line of hose fixtures with this style, and it can be utilized with metric-sized tubing. Design: ruthless seals such as those made by HIP, Autoclave Engineers or Butech utilize a metal-to-metal seal that provides the capability to visit very high pressure. The solid male -ring face seal fitting will mate with a swivel female -ring face seal suitable only.
