Wafer high performance butterfly valve provides a cost-effective solution for a wide range of applications where bubble-tight shut-off is required. Utilizing an eccentric disc and offset shaft, the design incorporates the flexible-lip sealing system into a lightweight, compact body. The result is that in many cases the valve can replace globe valve and gate valve yet easier operating, longer lasting and lower cost.
Axial flow check valves were developed in 1930. Its development was inspired by near-ideal design requirements: a check valve that can meet the requirements of different operating conditions with high zui reliability and low zui maintenance and operation costs.
Structural features of soft sealing plug valve:A. According to the use of temperature and working medium F4, F46, PVDF, PP, PO, PE and other self-lubricating material bushing, good lubrication, in the whole process of the sealing pair of small friction coefficient, plug flexible operation, long service life.
Features of electric globe valves
1. The fluid resistance is small, and the resistance coefficient is equal to the length of the pipe.
2. Simple structure, small size and light weight. Electric stop valve
The three-way ball valves are the professional’s choice for hydraulic flow control. The valves are constructed with a common port at the base of the valve body. Any of the three peripheral ports can be connected to the common port – the other ports are totally sealed. The 3-way ball valves are available in L-port or T-port configuration. T-3 orthogonal channels allow each other to cut off China Unicom and the third channel, from triage, the role of collusion. L-type can only connect the two orthogonal channels, while maintaining the third can not be inter-connected channels, only a distribution function. 3-way ball valves can be operated by rotary actuators. The actuators are controlled by a standard voltage for on/off, modulating, or floating point control which moves the valve to the position dictated by the control system.
The structure and application of the center line butterfly valve have the following points: 1. Adopt two-section valve stem without pin connection, simple and compact structure, extremely convenient for maintenance and disassembly (on-site disassembly);
