200/300 Series Multiport Needle Valves
NOSHOK 200 and 300 Series Multiport Needle Valves are engineered to eliminate multiple fittings, reduce installation labor, and dramatically minimize potential leak paths in process instrumentation piping. Featuring a single inlet and three outlet/gauge ports, these valves allow simultaneous mounting of pressure gauges, transmitters, calibration ports, or bleed valves. The 200 Series delivers rugged metal-to-metal hard seat shut-off rated up to 10,000 psi, while the 300 Series provides bubble-tight soft seat shut-off rated up to 6,000 psi with replaceable Acetal, PEEK, or PCTFE seats. Both series feature 100% helium leak testing, blow-out proof 316 stainless steel stems, rolled threads, and full NACE MR0175 compliance on 316SS models.
Multiport geometry (1 inlet, 3 outlet ports) eliminates extra tees, reducing leak points and installation space

Engineering & Safety Operating Notes
Multiport 1-inlet × 3-outlet architecture reduces leak paths by up to 60% compared to conventional pipe tee and nipple assemblies.
When selecting PTFE (P1) or Graphite (P2) compression packing, the maximum system pressure rating is 6,000 psi.
All 316 Stainless Steel valves comply with NACE MR0175/ISO 15156-3 requirements for sour gas service.
Slotted spring pin positively secures bonnet to valve body, preventing accidental disassembly under pressure.
Product Description
The NOSHOK 200 and 300 Series Multiport Needle Valves provide a compact, highly reliable piping solution for instrument isolation, testing, and venting. By incorporating three female outlet ports opposite or adjacent to the male process inlet, operators can install a primary pressure gauge or transmitter alongside a calibration port, bleed valve, or test plug without assembling complex manifolds of pipe nipples and tees.
Each valve is 100% factory helium leak tested to 1 × 10⁻⁴ ml/s to guarantee hermetic performance. The blow-out proof stem design incorporates secondary stem sealing in the full-open position, while stem threads are precision-rolled to maximize cycle life and minimize operating torque. A slotted spring pin locks the bonnet in place to eliminate accidental bonnet back-off during field operation.
Standard Multiport layout features one male process inlet and three 1/2" NPT female gauge/bleed connections
Hard seat 200 Series handles extreme pressures up to 10,000 psi, harsh process fluids, and elevated temperatures
Soft seat 300 Series provides bidirectional, bubble-tight zero-leakage shut-off with roddable straight-through orifice
Standard FKM O-ring stem seal with PTFE back-up ring positioned below threads to isolate lubrication from process media
Optional PTFE or Grafoil compression packing glands available conforming to MSS SP-99 and MSS SP-132 standards

Application & Engineering Notes
Multiport valves eliminate up to three individual threaded joints and the associated tees/fittings normally required to connect an isolation valve, local pressure gauge, transmitter, and bleed port.
When selecting packing options (P1 or P2), the maximum system pressure rating is 6,000 psi. Always refer to the Pressure vs. Temperature packing compatibility charts for extreme temperature applications.
Compatible with optional NOSHOK Bleed Plugs (BP Series), Bleed Valves (BV Series), and Hex Plugs for complete assembly customization.
Standard handle material matches valve body material (Steel handle on MFC, 316 Stainless Steel handle on MFS).
Acetal soft seats provide exceptional chemical resilience and roddability; upgrade to PEEK for higher chemical and temperature limits.
