18 Inch Valve
18 Inch pipe gate valves
will be used less often than 18-inch butterfly valves
because the 18-inch gate valves
price will be higher than butterfly valves
. The large diameter of the site to adjust the flow or pressure will be used in the pump control valve
. It has high safety and reliability. It has three measures to eliminate water hammers, such as quick closing, slow closing, and energy absorbing chamber. Besides, the action is fully interlocked, and no wrong action will be generated.
The multi-function pump control valve fully uses the pressure difference of its own pressure water to realize the fully automatic opening and closing operation of the valve. Whole process automatic control without any oil pressure, electrical equipment, and other auxiliary control facilities; There is no need to operate the additional distribution control system for the valve. When the pump starts and stops, it skillfully uses the pressure change of medium before and after the valve to control the power, so that the valve can automatically operate according to the requirements of the pump operating procedures, so as to achieve the automatic effect, which improves the working efficiency and greatly saves manpower and material resources; There is no need for professional debugging, easy installation and easy operation, the valve action is not affected by pump head and flow change, making it play a greater role, so it has a wide range of adaptation, and the valve basically needs no maintenance. Once installed, as long as normal use and necessary maintenance, the service life will be greatly extended. Pump control valve is a kind of hydraulic control valve diaphragm and diaphragm with a natural rubber production of raw materials, intermediate intensive nylon net, its action in more than 2 million times without damage, you can use the energy-saving effect is obvious, at least 20 years using imported into the pressure of diaphragm to support the weight of the diaphragm pressure plate and the valve stem, thus to achieve the purpose of reducing resistance loss as far as possible.
