The Smith Meter Model 210 Valve is a 200 Series valve with two solenoid controls, used with a Smith Meter AccuLoad or microLoad preset controller for loading and unloading at truck racks, bulk plants and processing installations. A normally-open (30B) and a normally-closed (30A) solenoid in the control loop open, close or lock the main valve so the controller can hold a set flow rate and run a programmed low-flow start, high-flow and multi-stage shutdown. Needle valves between each solenoid and the main valve tune opening and closing speed and isolate the control loop for service. The design is fail-to-close. A 2" reduced-port version controls flow down to 3 GPM for renewable-fuels blending.
Key specifications
Sizes / weight: 2" and 2" RP (46 lb), 3" (83 lb), 4" (136 lb), 6" (260 lb)
Pressure rating / connections: Class 150 ASME, 285 psi (19.6 bar); Class 300 ASME, 300 psi (20.7 bar), at -20 to 100 °F
Maximum viscosity: 200 SSU (40 mPa·s); above 200 SSU consult factory
Elastomers / temperature: LS Buna (standard) or Buna-N: -20 to 200 °F (-28 to 93 °C); Viton: -20 to 350 °F (-28 to 177 °C)
Solenoid voltage: Standard 120 VAC 60 Hz or 110 VAC 50 Hz; optional 240 VAC 60 Hz / 220 VAC 50 Hz, 24 VDC or 12 VDC
Materials: Cast steel main valve with stainless steel, carbon steel, Ni-Resist and ductile iron internals; stainless steel solenoid valves (Viton-F standard, Buna-N, Chemraz); steel needle valves, tubing and fittings (stainless optional); optional ball valves on 4" and 6"
Reverse flow / thermal relief: Reverse flow through the seat occurs when downstream pressure exceeds upstream by about 2-6 psig (size dependent); the optional 80B/07A check / pressure relief combination blocks reverse flow and relieves excess downstream pressure through the cover instead
Pressure drop: Chart given for 2", 2" RP, 3", 4" and 6" (kerosene, 0.82 SG); 2" and 2" RP negligible below 50 GPM when not flow-limiting
How to specify / order
The bulletin has no position-by-position model code. To quote, send:
Valve size (2", 2" reduced port, 3", 4" or 6") and flange class (150 or 300)
Product, viscosity and the maximum and minimum flow rates (the pump must be able to reach the flow rate set in the preset)
Elastomer choice (LS Buna, Buna-N or Viton) and solenoid voltage
Options: 80B/07A check / pressure relief, stainless steel tubing, fittings or ball valves
The preset controller in use (AccuLoad or microLoad)
Bulletin notes: The dimension table prints the 2" pilot-envelope dimension D as 7.5 in (140 mm); 7.5 in is about 191 mm. Related part listings on this store include the Model 210 N.O. solenoid part-number notices 645805-412 and 645805-413.
