Zhejiang Galaxy Machinery Manufacture Co. Ltd

Model Number: YH0012-004 EP57 Brand Name: Galaxy / Yinhe Key Specifications/Special Features: Emergency oil hold back valve Installed on fuel supply lines beneath at grade level to minimize hazards associated with collision or fire at the dispenserUsed together with submerged oil-pump type fueling machineCan cutoff oil flow automatically and rapidly and protection for submerged oil-pump type fueling machine

Single-poppet models shut off supply flow, while double-poppet models shut off supply as well as prevent release of fuel from the dispenser's internal piping

Adapts fusible material and cutting ring

Valve core will close automatically to cutoff oil-flowing pipe in case of catching fire or oiling machine damaged by knocking

Features:

• Threaded outlet of upper body is convenient for connection with flowmeter of fueling machine
• High temperature pressure relief valve is used to relieve pressure with temperature of oil in pipeline due to cutoff of close of auxiliary valve when oiling machine breaks down
• Normally open type auxiliary valve can stop oil reverse flowing when it is closed
• Holder can make auxiliary valve normally open to reduce of oil flow and that will not affect its flux
• Spring is used to strengthen sealing performance when auxiliary valve
• Cutting ring is cutoff under stress and ensures cutoff moment of 350
• Main valve is used to close oil flow to oiling machine from oil pump
• Main body is made of HT200 cast iron and inside or outside threaded inlet is for option
• Testing jack is used to test pressure in pipeline after being installed with pressure meter
• Tumbler is holder to keep main valve normally open
• Uses special alloy
• Galaxy l# can ensure normal action under 75°C
