Barksdale Series L20517 pressure regulators
压力调节器
Series L20517 Description
Barksdale压力调节器是敏感的压力控制装置，用于在液压回路中保持预先确定的压力。调节的输出压力可以由弹簧或马达（液压或气动）的力控制。设计特点确保卓越的精度、重复性和高流量系数。Barksdale's pressure regulators are sensitive pressure-control devices used to maintain a pre-determined pressure in a hydraulic circuit. The regulated output pressure can be controlled either by the force of a spring, or a motor (hydraulic or pneumatic). Design features ensure excellent accuracy, repeatability and high flow coefficients.
设计用于提供多年无故障运行和几乎零泄漏，剪切密封?设计使用流体压力来保持无泄漏的金属对金属密封，随着使用而改进。转子和压力密封之间的剪切作用不断地重叠配合面，防止污染物在密封面之间倒伏。其结果是阀门不会磨损，但随着时间的推移会逐渐磨损，从而在产品的整个生命周期内为您提供始终如一的卓越控制。Designed to provide years of trouble-free operation and virtually zero leakage, the Shear-Seal? design uses fluid pressure to maintain a leak-free metal-to-metal seal that improves with use. The shearing action between the rotor & pressure seal continually laps the mating surfaces and prevents contaminates from lodging between the sealing surfaces. The result is a valve that doesn’t wear out – but wears in over time, providing you superior control consistently through the entire life of the product.
