Product Details

Watts 115-4 FL (LFF 115-4) pressure-reducing control valve is a self-operating valve that is used to remove excess pressure in a system. This valve automatically adjusts its opening to maintain steady pressure during surges. It is used in gas and water pipelines which deal with regular pressure fluctuation.

Working Mechanism

  • When the downstream pressure drops, the valve modulates towards the 'open' position to raise the downstream pressure.
  • When the downstream pressure rises, the valve modulates towards the 'close' position to lower the downstream pressure.

Features

  • Watts 115-4 FL pressure reducing control valve features automatic shut-off to reduce higher, fluctuating upstream pressure to a lower, constant value.
  • This unit features iron housing with an epoxy coating for resistance against chemicals.
  • It has an adjustable setpoint to handle varying pressure.
  • This unit also functions as a solenoid (On/Off) control valve that allows fluid-flow regulation in the 'Open' position and provides the drip-tight mode in the 'Close' position.
  • Its simplified and efficient design is easy to maintain.

Standards and Approvals

  • ASTM A536
  • NSF
