Principle Features
- Screwed Female Ends to BS:21 / IS : 554.
- Spring Loaded Piston Type design provided with high-quality Nitrile Rubber “O” ring to have less maintenance cost.
- Provision for pressure gauge is provided.
- Designed to suite precise applications requiring accurate pressure rating (pressure drop being less).
- Most ideal for Sensitive & a consistent fluid regulation.
- No external source of energy required.
- Very rugged type of construction leads to low damages and self-operating in nature.
- Can be installed at 360 Deg. Rotational Axis.
- Screwed Female Ends.
- Metal piston offers more life than conventional rubber diaphragm-type PRV.
- Compact Size, easy to install.
- Facility provided to install a pressure gauge of 1/4” BSP size to gauge the critically relevant outlet pressure.
- All ‘O’ rings are of superior food-grade material, hence ensuring absolute zero health hazard.
