Winters multiport (NVA series) and block-and-bleed (BBV series) needle valves feature a one-piece corrosion-resistant 316 stainless-steel or carbon body rated up to either 6,000 psi or 10,000 psi. The multiport valves have three output ports available that can accommodate up to three different instruments, while the block-and-bleed valves allow the user to drain the media trapped between the instrument and connection before removal from the system.
