High pressure self control valve ZZYK
ZZW/ ZZWLD SERIES CONTROL VALVE
ZZW/ZZWLD series self-temperature control valve is designed and manufactured under the market demand and present condition.
This series valve are not in need of any outside energy supply or temperature control system, owing to the inside warm bag filled with a fluid which itself physical and chemical nature or PT100 platinum RTD sensing could automatically close or start the valve and achieve the purpose of auto-control the temperature. This series is widely applied in heating watercryogen equipment.
This series products has ZZWP-16B(heating), ZZWP-16K(cooling), ZZWP-16K3(Three-way), ZDLWD(electric control type).
