V、VR series three valves manifold
Instrument valve (door) and pipe connection
Number of views:
·The structure of valve bank is total 316 stainless steel, which has high strength and high corrosion resistance.
·Can be customized according to the requirements of users.
·The design safety factor is 4:1
Structural integrity of valve bank
·The valve body adopts integrated-type structure, which has high overall strength.
·It is equipped with the safety shotpin so as to prevent the falling off of valve deck caused by misoperation or vibration.
·It adopts metal-against-metal rigidity sealing type between the valve deck and valve body.
·The standard gland packing of valve rod is PTFE (While using under high temperature, it is flexible graphite.)
·The valves uniformly adopt rotation-free spherical metal sealing form.
Internal finish degree
·Internal surface electrochemistry burring treatment
The connector type of valve bank adapting piece
·12mm ferrule tube connector
·1/2 in. ferrule tube connector
·1/2 in. NPT thread
·Direct instrument installation or remote installation, which can be conducted by using NPT thread connectors and bite type tube fittings.
·The sealing element of standard flange is fluorocarbon FKM O-ring.
·The valve bank with flanges includes flange bolts and flange sealing elements.
Before leaving the factory, each set of valve bank has passed the 7MPa nitrogen pressure test. There is no bubble produced in the shell and valve seat within 1min.
The flow passing the valve bank will be controlled by a series of needle valves. The specific functions of each valve (such as cut-off, discharge or balance pressure) will be determined by its position on the valve bank.
The valves of instrument valves manifold have two sizes: large and small. The small valve applies to the valve port with aperture Φ3.2, while the large valve applies to the valve port with aperture Φ4.0. All the valves adopt the rotation-free stainless steel balls as their sealing elements. The valve can realize the back sealing on the max. open position.
The compressing degree of valve rod packing can be adjusted externally. PTFE is the packing of standard configuration and the flexible graphite packing is used in the occasions with high temperature.

Smart differential pressure flowmeter is a smart flowmeter based on battery-powered low-power Internet of Things technology. It is mainly used for the detection of large-diameter water flow in urban water affairs and municipal pipe networks. It uploads collected water flow data and other information to the cloud server through a wireless remote
There are numerous municipal fire hydrants, scattered installations, destruction of fire hydrants, embezzlement of fire-fighting water, insufficient pressure of fire-fighting pipelines, and other problems. As a result,
WP304D temperature collector adopts MEMS temperature sensor chip to be encapsulated in a specific case. The temperature sensor and the conversion circuit are integrated to form a small special temperature sensor. Its appearance is small and exquisite, the measurement accuracy is high, the reliability is good, the power consumption is low,
