FOV Relief valve

Short Description:

FOV relief valve is a valve designed to prevent system vibration caused by low flow rate or low density. It can be applied to occasions where the refrigerating capacity changes greatly.It can control the pressure during defrosting, open the valve when reaching the set value, adjust the valve stem clockwise to manually adjust the spring pressure, and adjust the valve stem to close the valve until the spring is blocked.

Characteristics

1.FOV is a direct-current overflow valve with adjustable opening pressure, which has three functions: relief valve, one-way valve and stop valve.
2.The valve can be closed manually. With reverse sealing function, the valve stem sealing parts can be replaced under pressure. The high-precision O-ring ensures perfect sealing performance.
3.The set pressure is the pressure when the valve starts to open, which can be adjusted within the range of 2-8 bar differential pressure.
