The POSI-SEAL rotary valve (photo) is suited to on/off process applications requiring tight shutoffs. The pressure-assisting action of the valve seal ring enables complete shutoff. By minimizing contact between the seal ring and the valve disk, seal wear is reduced.…
Fluoroplastic Paratubing consists of two to four tubes thermally welded longitudinally to create one conduit of multiple, individual tubes. Paratubing enables running several fluid lines as one entity and then splitting the tubes apart for branching to different connectors. This…
Michael Smith Engineers The combination of FMI rotary piston pump and Ismatec drives results in a range of pumps (photo) for very accurate and reliable dispensing, even when highly aggressive chemicals or viscous media need to be transferred. The pump…

GEMÜ The new 537 manually operated globe valve (photo) uses the same valve body as the company’s 534 and 532 actuator designs. Valve bodies in nominal sizes DN 15–50 in cast-stainless-steel 1.4408 and SG iron GGG 40.3 (EN-GJS-400-18-LT) are available.…
The Quantum Series four-way, wye- line diverter can direct powder, pellets or granules from one source to four destinations or converge from four sources to one destination. It is engineered to handle dry bulk solids in pneumatic conveying systems with…
Launched in April, this new generation of diaphragm valves (photo) is said to have a number of decisive advantages in handling and safety, but also in regard to efficiency. The flow in these valves is, on average, double that of…
MKS Instruments The High Cycle Valve (photo) is a durable vacuum valve designed for demanding applications where a long cycle life is critical. The small, light and durable valve is rated for 10 million cycles, and is available with an…
The SL Submersible Pump range offers two types of impellers to handle a wide range of process and wastewater applications. The SuperVortex Impeller provides free passage of solids up to 4 in. in diameter, making it ideal for liquids containing…
Michael Smith Engineers The Finish Thompson EF drum pump (photo) includes a shorter 16-in. tube length option that is ideal for transferring liquids, such as oils, acids and detergents from small drums, buckets and carboys. The pump is capable of…
