Self-operated Regulators with Pilot Valve
Brief DescriptionType 5813 self-operated regulators with pilot valve(referred to as a pressure valve) without external energy, use the energy of medium itself as the power sour, to introduce the pilot to control pressure valve spool position,changing the medium flow throu
Details1.Pressure setting implemented on pilot,Thus it is convenient, time-saving and can be set in continuous operation status
2.Control precision is 1 times higher than ZZY type Self- operated , it is suitable for use where high accuracy in control
3.On the same valve, the adjustment range is more broad-based than type 5811 self-operated Pressure Regulator
4.Reaction is particularly sensitive to small pressure (e.g., 50mm water column pressure), or small pressure changes can be infected out
5.Pressure ratio is particularly large, such as the former valve value is 0.8MPa, and then the valve value is50mmH20, Pressure differential value is 160!
