Valves and Regulators
Safety Relief Valves
WNS Lowery’s 2500 Series Safety Relief Valve (SRV) offers a top-of-the-line economical pressure relief valve. The 2500 SRV is engineered to operate in a variety of general-purpose gas and liquid applications. The 2500 SRV is manufactured and tested in accordance with the ASME Boiler and Pressure Vessel Section XIII. Flow capacities are tested and independently certified by the National Board to ensure proper function and relief capacities. All certified valves are stamped with the symbols “UV” and “NB” to signify they were assembled and tested in accordance to ASME code requirements.
Back Pressure Regulator
The WNS Lowery Series W770 Back Pressure Regulator (BPR) offers an affordable solution for maintaining a constant back pressure and an automatic relief of pressure in liquid or gas applications. By maintaining a constant and reliable back pressure on the oil column, this valve ensures gas bubbles do not break out of solution and reduces the paraffin build up in the well. The decrease of gas pockets in the oil also provides a continuous lubrication of the polished rod, extending the life of the stuffing box cone packing, while also enhancing the efficiency of the bottom hole pump.

Balanced Back Pressure Regulator
The WNS Lowery Series W772 Balanced Back Pressure Regulator (BBPR) offers an economical solution for automatic relief of pressure in liquid or gas applications. The spring balanced design regulates pressure based on the upstream conditions while remaining unaffected by downstream pressure.
