- Edwards Speedivalve
- Screw-Based Open/Close System
- Fluoroelastomer Diaphragm
- High-Durability Valve
The Edwards Speedivalve SP16K is a diaphragm sealed in-line, isolation valve. The construction consists of a flexible elastomeric diaphragm which is sealed onto a polished seat by a screw mechanism. The Speedivalve's mechanism is isolated from the system by the diaphragm resulting in an extremely high-durability and ‘dirty’ system tolerant valve.
The SP10k, SP16k, SP25k, and SP40k valves are available with either fluoroelastomer or nitrile rubber diaphragms.
The valve body is made from aluminum and the complete valve is leak tight to better than 1 x 10^-6 mbar.ls^-1 and 1 bar differential.
These valves have NW flanges and are suitable for pipeline or panel mounting.
These valves are built to withstand an ambient operating temperature range of 0-40 Degrees celsius.
