1. As the channel within the valve is in streamline form, the flow resistance is smaller than lifting check valve, it's suitable for low flow large-caliber application without frequently change in flow. However, it's not suitable for pulsating flow for sealing performance poorer than lifting check valve.
2. Swing check valve is suitable for various operating conditions of pipeline for petroleum, chemical, pharmaceutical, chemical fertilizer and electric power industry.
3. Swing check valve is suitable for clean medium like water, oil, steam, acid medium, and not suitable for medium with solid particles and great viscosity.

Gate ValveMore >>
Plate gate valve is a kind of sliding valve that taking parallel flashboard as closing element. The closing part may be single flashboard or double-flashboard with support mechanism in the middle.
Straight plate gate valve may be divided into single flashboard plate gate valve without and single flashboard plate gate valve with diversion hole. The latter is usually for long-distance transportation pipeline, and the former is mainly for entrance and exit within station or pump.
Plate gate valve has compact structure, small flow resistance. It's easy to operate and suitable for natural gas, petroleum, chemical industry, environmental protection, city pipeline, gas pipeline and other pipelines, blow-down system and gas storage system as on-off equipment.
Plate gate valve is also suitable for medium with suspended particles as the flashboard slides on surface of the two valve seat.

Global ValveMore >>
Globe valve uses valve stem pressure to make the sealing face of valve clack and sealing face of valve seat fit tightly to cut off medium. It's a forced seal valve. Flow direction of medium in globe valve includes "low in and high out" and "high in and low out". The medium is allowed to flow in only one direction. The valve shall be installed in right direction. Globe valve has structure of straight-through type, direct flow type and right angle type.
When globe valve is open, and the opening height of valve clack is up to 25% ~ 30% of nominal diameter of the globe valve, the flow reaches the maximum which show that the valve reaches the fully open position.
