KF系列压力表开关是小型的截止阀或节流阀，用来切断压力表和油路的连接或调节开口度大小。它是有阻尼作用可减轻压力表急剧跳动，防止损坏，也可当作一般小流量的截止阀或节流阀使用。压力开关的工作原理：是当系统内压力高于或低于额定的安全压力时，感应器内碟片瞬时发生移动，通过连接导杆推动开关接头接通或断开，当压力降至或升额定的恢复值时，碟片瞬复位，开关自动复位，或者简单的说是当被测压力超过额定值时，弹性元件的自由端产生位移，直接或经过比较后推动开关元件，改变开关元件的通断状态，达到控制被测压力的目的。

JZFS Hydraulic Globe Valve - Product Overview

The JZFS Series Hydraulic Globe Valve is a high-precision control valve designed specifically for hydraulic systems. It is mainly used to achieve precise shut-off, throttling regulation one-way flow control of high-pressure fluids, is widely applicable to scenarios such as construction machinery, metallurgical equipment, hydraulic stations, capable of stably handling high-pressure working conditions of media like hydraulic oil emulsion.

This series of valves has a nominal pressure range of 16MPa-31.5MPa an operating temperature range of -25℃-150℃, adapting to the pressure requirements of different hydraulic systems. The valve body is made of forged steel stainless steel, with strong resistance to high-pressure impact medium corrosion; the valve core is precision-ground matched with nitrile rubber fluororubber sealing components, which has both reliable sealing performance low friction loss, effectively reducing fluid leakage ensuring stable system pressure. The connection method is mainly thread connection (such as G, NPT threads), some models support flanged installation to adapt to various pipeline layouts; the operation method is mostly manual (equipped with a rotary steel handle), the flow rate is fine-tuned by adjusting the valve core stroke. Some models can be integrated with hydraulic pilot control to meet the remote operation needs of automatic systems, are especially suitable for key nodes in hydraulic circuits that require precise control of medium flow fluid shut-off.
