Product Description

ZZVP Self-operated Micro Pressure Control Valve


Self operated control valve Product Introduction

ZZVP self-operated micro pressure control valve is energy saving valve without external energy, it uses the compare with the pressure changing and signal in the medium, so that the force of the regulated medium and the output force of the actuator balance, to stable the pressure and the differential pressure value. ZZCP-1 series differential pressure valve adopts the balance type single seat body, stable pressure, high precision, well sealing, to control the micro differential pressure. ZZCN-10 type differential pressure valve adopts double seat body, large flow coefficient. It compose of two different varieties of regulating valve products by normally and inverse install the core.
The product is suitable for kinds of combustion system of industrial furnace to control the mixed ratio of two kinds of fuel gas flow or used in sealing oil system of the hydrogen cooling generator set, it can also be used for controlling kinds of reducing pressure, stable pressure, decompression of industrial gas decompression.
