● Product overview
The manual pressure gauge button valve is a multifunctional valve that integrates pressure monitoring and fluid (gas/liquid) on-off control. It achieves quick opening and closing through manual button operation and displays the system's pressure value in real time. Suitable for scenarios requiring synchronized monitoring of pressure status and precise regulation of fluids, such as hydraulic systems, pneumatic equipment, industrial pipelines, and laboratory testing devices.
● structural composition
-Valve body: the valve body is made of brass, which is resistant to pressure and corrosion, and integrates pressure gauge interface.
-Button control mechanism: press design, mechanical linkage valve core opening and closing, support the lock operation mode.
-Pressure gauge assembly: standard mechanical pressure gauge (optional digital gauge), range covering 0~60 MPa, accuracy class 1.6.
-Sealing system: fluororubber (FKM), polytetrafluoroethylene (PTFE) or metal hard seal, suitable for different media.
-Connection port: NPT thread, G thread or flange interface, suitable for two-way connection between pressure gauge and pipeline.
● operational principle
-On-off control: press the button to drive the valve core to move, open or close the fluid channel.
-Pressure monitoring: the valve is connected to the pressure gauge to provide real-time feedback of the system pressure, which is displayed on the dial pointer or digital screen.
● Core features
-Integrated design: the valve and pressure gauge are integrated to save space and reduce the risk of pipeline leakage.
-Dual-function operation: one-button control of fluid on and off, synchronous monitoring of pressure changes, improve the efficiency of operation.
-High precision measurement: pressure gauge accuracy ±1.6%, response time less than 0.5 seconds, suitable for dynamic pressure monitoring.
-Safe and reliable: overvoltage protection design (some models with pressure relief valve), pressure resistance up to 60 MPa.
-Multi-medium compatibility: support air, water, oil, steam and weak corrosive liquids (corresponding sealing materials are required).
-Flexible adaptation: pressure gauge can be replaced (such as mechanical gauge to digital gauge), support customized range and unit (Bar/MPa/PSI).
● application area
-Industrial hydraulic system: pump station pressure debugging, pipeline pressure monitoring and emergency cutting.
-Pneumatic equipment: air compressor, cylinder circuit pressure real-time display and flow regulation.
-Laboratory tests: fluid pressure test, leak detection and safety relief control.
-Energy industry: boiler steam pressure management, gas pipeline maintenance.
-Water treatment system: high pressure cleaning equipment, filtration backflush pressure control.
● Installation and maintenance
-Installation points:
-Ensure that the pressure gauge is oriented towards a visible position and avoid vibration or direct exposure to high temperature.
-The inlet and outlet direction of the valve is consistent with the flow direction of the fluid (arrow marked on the valve body).
-maintenance overhaul:
-Regular calibration of pressure gauges (recommended every 6 months).
-Clean the surface of the valve body to prevent impurities from blocking the valve core.
-fault treatment:
-When the pressure gauge reading is abnormal, check whether the pipeline is blocked or the seal fails.
-The button is stuck and the valve stem needs to be lubricated or the seal ring needs to be replaced.
● matters need attention
-Pressure matching: Select a pressure gauge whose range is 1.5 times higher than the maximum pressure of the system to avoid overload damage.
-Medium compatibility: corrosive medium should be selected with 316 stainless steel valve body +PTFE seal.
-Operation specifications: repair the valve after pressure relief to prevent high-pressure fluid from splashing.
