Safe sampling solution
The problem of obtaining process samples from reactor vessels without requiring process shutdown has been solved by the PV vessel sampling device from Neotecha, giving more accurate results
Combining smooth flow characteristics with excellent abrasion, erosion and corrosion resistance, the OptiSeal range is designed for applications requiring a maximum flow area and bubble-tight shut-off.
The OptiSeal rounded and polished disk edge provides the absolute minimum obstruction to flow (up to DN 300), while allowing for full concentric sealing, lower torques and prolonged seat life.
To ensure no process media becomes trapped within the valve, it is constructed with a crevice-free internal contour, and a relief hole to drain any fluids from the top plate recess space (to DN 300).

High quality reliable economical butterfly valves
Tyco Valves and Controls has introduced a series of new, high quality, reliable and economical butterfly valves for general purpose industrial applications, the PremiSeal range
The field-replaceable seat fully isolates the valve body from the flow, and incorporates a moulded-in O ring for flange sealing, removing the need for gaskets.
The valve body is sealed against leakage to the seat.
The shaft is triple protected; primary stem sealing exceeds the valve pressure rating preventing any leakage to atmosphere, a secondary shaft seal is fitted, and a dirtscraper eliminates moisture penetration into the shaft.
The OptiSeal is available with a wafer or lugged body, according to ISO 5725/5 short (DIN 3202, part 3/K1).
Lugged versions are capable of handling all pressure testing applications during installation and commissioning phases.
All OptiSeal valves conform to PED 97/23/EU Module H, and are approved to a range of international standards including CE Marking, FDA, KTW/DVGW, KIWA, DGS, ABS and DNV.
Body locating holes simplify installation and centring between flanges.
The design also includes an integral actuator flange to ISO 5211, and top bushing to absorb actuator side thrust loads.
Several options are available to tailor OptiSeal to specific applications; a certified EPDM seat is offered for drinking water applications, PTFE lined seats and PTFE covered disk stems are available for applications which require high chemical resistance and non-toxic properties, and grease- or silicone-free valves can be specified for special applications involving paint or oxygen systems.
The OptiSeal range is rated to pressures of 16 bar for both standard and end-of-line service.
It is suitable for use with temperatures from -40C to + 160C.
Sizes range from 40-900mm, with flange accommodation to PN 16, ANSI 150 and JIS 5K/ 10K.
