High-pressure reduction needs often put a wrench in your sampling. Ensure you are facing your high-pressure issues head on with the VREL Control Valve.
Pressure rated for up to 5000 psi (345 bar), this stainless-steel valve drops pressure smoothly with no disruption. The VREL's conjoined tube high pressure reduction valve ensures operators maintain the required pressure and flow with an external knob. It has become the industry standard for samples greater than 500 psi (34.5 bar) according to ASTM Standards.
The Sentry VREL control valve consists of two stainless steel tubes joined to a large tube or barrel. A tapered rod assembly is inserted into precision holes in the barrel. The high pressure fluid enters, flows past one rod, turns and flows past the other rod, and then out. Pressure drop is a function of the length of the rods insterted in the barrel. The pressure is reduced smoothly under laminar flow conditions, minimizing dissociation of any components through discontinuous pressure drops. The rod position is controlled externally by turning the knob, and can be adjusted while sample is flowing. If a blockage occurs, the rod can be reached so system pressure can blow the sollid matter through.

- The VREL control valve is cleanable in place, reducing the need for a shutdown to clean.
- Removing solids is easy with retractable rods for blowdown.
- Simple control design maximizes operator control overflow and pressure.
- A large flow rate differential (capabilities from 150 mL to 4 L per minute) ensures you are meeting the needs of your process.
- The large rod-in-tube design allows for variable pressure drop and flow control.
