It's no secret that OEMs want hydraulic controls that simplify mobile-equipment design and are versatile enough to handle a range of applications. Modular load-sensing valves fit this bill and are an ...

Stanwell Power Station, a 1,460-MW coal-fired power plant located in Queensland, Australia, faced a dilemma. The reliability of its fire protection system was questionable. Many of the plant’s ...

• Standard solenoid valves pose an ignition danger near hazardous materials. • Valves with pneumatic and magnetic actuators require no electricity, making them inherently safe in hazardous locations.

There aren’t many technologies as ubiquitous in cycling as the Presta air valve. So it’s surprising that, in the roughly 100 years since its invention, it’s basically never changed. Until now. A new ...
