Upstream Control Valves

Nirmal's upstream control valves — also known as back pressure regulators — maintain a constant set pressure on the inlet side regardless of fluctuations in flow or downstream conditions. Available in self-operated and pilot operated designs for a wide range of fluids and pressures.
