Description


A valve is a mechanical device that controls the flow rate, flow direction, pressure, temperature, etc. of a flowing fluid medium. Valves are the basic components in piping systems. Valve fittings, like pumps in technology, are often discussed as a separate category. The valve may be operated manually or with a hand wheel, handle or pedal, and may also be controlled to vary the pressure, temperature and flow rate of the fluid medium. The valve can perform continuous or repeated operations on these changes, such as safety valves installed in hot water systems or steam boilers. In more complex control systems, automatic control valves are used as required by external inputs (I. e., to adjust the changing set point of the flow through the pipeline). The automatic control valve does not need to be manually operated according to its input and setting, so that the valve can accurately control the various requirements of the fluid medium. Valves can also be divided into cast iron valves, cast steel valves, stainless steel valves, chromium molybdenum steel valves, chromium molybdenum vanadium steel valves, dual phase steel valves, plastic valves, non-standard customized valve materials, etc.

◆ Product overview

RVMX magnetic anti-theft gate valve according to the "permanent magnet rotation no leakage theory", the use of push-pull magnetic circuit optimization design scheme, the traditional valve opening and closing operation of the mechanical force into permanent magnet torque, because the opening and closing mechanism closed inside the valve fundamentally put an end to the leakage of the valve. The anti-theft performance of the valve can achieve zero leakage, easy switch, stable sealing effect, long service life and so on. With "permanent magnet leakage-free transmission technology", the opening and closing system is sealed inside the valve body, and the special handwheel is rotated to complete the opening and closing operation of the valve, thus eliminating the leakage. There is no mechanical connection between the special handle and the valve stem, and the handle can be removed and taken away after the operation, which can avoid misoperation and prevent theft, and is convenient for control and management. Realize "one valve, one key" and one valve, one key "; due to the valve to achieve full sealing mechanism, cancel the packing, reduce the valve stem wear, so that the valve opening and closing flexibility, and will not rust to death, prolong the service life of the valve; due to the elimination of leakage, improve the use of the site of the working environment, to solve the problem of pollution on site, is an ideal green valve.
