VR-01
Poppet Check Valve (FxF) Working Pressures: 100 \| 210 bar (1500 \| 3000 PSI)
TECVAL VR-01 poppet check valves are designed to work with liquids under both high pressure and temperature service. They open at a fixed low pressure and close immediately the moment the flow reverses. They are commonly used in chemical plants, water treatment plants, refineries, laboratories and power stations, as well as in general industry.

Special alloys

Among the wide range of alloys existing, TECVAL has selected those considered by our customers as most suitable, which we stock to ensure a quick and effective supply. Whether you do not find the required alloy or need further information about our special alloys valves and fittings, please address your inquiry to our Technical Department.

Elastomers & Seats

Poppet O-ring (position 5) can be made of different materials (NBR, EPDM & NEOPREN) upon request, considering the working conditions and fluid of the valve. For further information, please contact our Technical Department.

Poppet O-Ring * / Safety lock nut *

Poppet O-Ring *: In order to provide a perfect seal, our VR-01 valves in standard version are equipped with O-ring in poppet from dimensions 1¼”" to 3".
Optionally, the dimensions from 1/4" to 1" can also incorporate this type of closure. R

Safety lock nut *: To avoid accidental detachment of the top cap, VR-01 valves incorporate a safety lock nut in dimensions from 1¼”" to 3".
