  • All You Need To Know About Power Plant Valves - XHVAL Valve

    Valves Typically Used in Power Plant ApplicationsValve Classification in The Power Plant IndustrySummaryBolted Bonnet and Pressure Seal Gate ValvesGate valves have a disc or wedge that acts as a gate that blocks the flow path of media. Not intended for throttling, the main role of gate valves is for isolation of media with less restriction. To fully utilize the gate valve, only use it as fully opened or fully closed. Gate valves, together with the globe valves, belong to tBolted Bonnet and Pressure Seal Globe ValvesThe globe valve is quite similar to the gate valve but instead of a wedged disc, it employs a globe-like disk that shuts off, turns on or throttles media. Primarily, this kind of valve is for throttling purposes. The downside of the globe valve is that it cannot be used with media with high flow rates. The globe valves, Bolted Bonnet Swing Check or Pressure Seal Tilt Disc Check ValvesCheck valvesare anti-backflow valves. What this means is that it allows a unidirectional media flow. The 45-degree angled disc design reduces water hammering as well as can adapt to media with high velocity. Also, the design allows a low-pressure drop. Check valves protect the entire piping system and equipmSee more on xhval
