Barksdale Series S20517 pressure regulators
Series S20517 1- ” Stainless Steel Pressure Regulator
S20517系列1-1/2“不锈钢压力调节器
Heavy Duty Shear-Seal Regulator for Offshore
海上重型剪切密封调节器
Series S20517 Description
Barksdale的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。不锈钢调节器提供耐腐蚀、316不锈钢、带SAE J518-2规范62法兰的装置，这些是本系列的标准。代码62法兰是经过工业验证的无泄漏连接，适用于更高的压力，便于安装。Barksdale's pressure regulators are sensitive pressure-control devices used to maintain a pre-determined pressure in a hydraulic circuit. The Stainless Steel Regulators offer corrosive-resistant, 316 stainless steel, units with SAE J518-2 code 62 flanges, which are standard with this series. Code 62 flanges are industry proven leak-free connections suited for higher pressure that offer ease of installation.
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.
