MVBB series single block-and-bleed needle valves
MVBB series single block-and-bleed needle valves have a small valve body. They perform calibration operations by providing controlled flow to high-pressure hydraulic and pneumatic systems through both shut-off regulation and diversion. DBB series double blockand-bleed needle valves are made from cold-worked stainless steel or from 17-4-H1075 (which is Type 630 alloy that has been heat-treated at 1,065°F to 1,085°F for 3.75–4.25 h). DBB valves are suitable for pressure monitoring, chemical injection, and drain-line-isolation applications. Both series offer safe and reliable operation up to 20,000 psi. 

NPT valves and fittings
Constructed from high-tensile Type 316 stainless steel, NPT valves and fittings in this product line are offered in two-way straight and two-way angle body configurations. Sizes for the valves, in inches, include 1/8, 1/4, 3/8, 1/2, 3/4 and 1. Fittings are available as elbows, tees and crosses to accommodate either 10,000 or 15,000 psi and all the NPT tubing connection sizes.
