Parker Valve FS190 Excess Flow Shut Off Valve
Product Description:
Parker Hannifin Veriflo FS190: The Ultimate Excess Flow Shut - Off Solution Discover the Parker Hannifin Corporation’s Veriflo Division's FS190, a revolutionary non - attitude sensitive excess flow shut - off valve. It's engineered to handle a wide range of inlet pressures, from 10 to 3500 psig, making it suitable for use between high - pressure sources and pressure regulators or in low - pressure delivery lines. If the gas flow exceeds a preset limit, the FS190 automatically cuts off gas delivery, ensuring safety in various processes. With its components integrated into a 1 - 1/4 inch Quantum valve body style, it's both compact and reliable. The actuating knob allows for easy manual reset and clearly shows the operating position. For added convenience, a pneumatic actuator option enables remote resetting. Offered with six different pressure/flow limits (A - F), the FS190's operation remains unaffected by its mounting orientation. Ideal for industries like manufacturing, energy, and chemical processing, the FS190 is a top - notch choice for flow control and safety.
