Luofu Valve Group Co., Ltd products

Pressure Safety Valve With changeover valve(single control) is composed of one switching valve and two spring type safety valves in parallel, with the same inlet. By switching the device, one safety valve can operate and the other safety valve can be closed, and the two safety valves can take turns switching to the working state. The switching device can be equipped with different types of safety valves according to the different media, temperature, and pressure used to adapt to different working conditions. The inlet and outlet flanges of the switching safety valve can adopt national or American standards according to user requirements. The safety valve should be installed vertically and installed at the gas phase interface position of the container or pipeline.

Prussure Safety Valve With changeover valve(double control) consists of a switching valve and two safety valves. The safety valve can be replaced or repaired, and the safety valve can be checked without stopping the operation of the equipment, and the double-switching valve group linkage control can be adopted as required. Prussure Safety Valve With changeover valve(double control) has more names as follows depending on what they are called: Switching safety valve,Double Switching Safety Valve,Switch Valve For safety equipment,PSV Switching Valve

The GRK series vertical hanging cover manhole is installed under the walls of storage tanks in petrochemical, pharmaceutical, food, and other industries. It serves as the entrance and exit for workers during tank construction, cleaning, and pouring. The strength and sealing of the manhole are the technical keys. The vertical hanging cover manhole is mainly installed on the side wall of the tank for the entry and exit of workers.

The function of GSP with drainage pipe and drain hole: Install a drain hole with a drainage pipe in the light oil tank. When cleaning the tank, sludge can be discharged from this hole. Usually, the sewage inside the tank can be discharged from this drainage pipe.

Through the throttling of the opening and closing parts, the threaded pressure reducing valve Y12X/F causes pressure loss to force the inlet pressure to reduce a certain required value at the outlet. When the flow and pressure change, the purpose of using its own medium energy to control the outlet pressure is basically unchanged. .

The proportional pressure reducing valve has beautiful appearance, reliable quality, accurate ratio, stable operation, and reduces both dynamic pressure and static pressure. The valve uses the pressure difference generated by the different cross-sectional areas of the piston inside the valve body to change the pressure after the valve to achieve the purpose of reducing pressure. The pressure reducing ratio of the pressure reducing valve is: 2:1, 3:1, 4:1, 3:2, 5:2, etc. The pressure reducing valve with a special ratio can also be designed according to the requirements of users.
