Valve Positioners and Accessories MK10
Mounting
- surface, flush panel, pipe supported or valve mounted
Connections
- standard back connections are 1/4" FNPT
Measured Indications
- black adjustable pointer on 3-1/2" precision gauge dial (6-3/4" scale length). Readily adjusted to compensate for hydrostatic heads in piping on pressure control applications.
Ranges in Stock
- 0 - 30 psi (0 - 2,1 bar)
- 0 - 60 psi (0 - 4,1 bar)
- 0 - 100 psi (0 - 6,9 bar)
- 0 - 200 psi (0 - 13,8 bar)
- 0 - 600 psi (0 - 41,4 bar)
Nozzle
- nickel silver, can be turned on turret to reverse control action, 0.018" bore
Orifice
- Sapphire 0.008" bore with integral push-button cleaner
Air Supply Pressure
- 20 psi for 3-15 psi range (1,4 bar for 0,21 - 1,03 bar range)
- 35 psi for 6 - 30 psi range (2,4 bar for 0,4 - 2,1 bar range)
- 65 psi for 12 - 60 psi range (4,5 bar for 0,8 - 4,1 bar range).
Relays
- a high capacity, non-bleed type relay is furnished as standard on these controllers. Bleed rate of less than 0.1 scfm at 9 psi (0.003N/m3 at 0,62 bar) at output and the capacity to deliver over 3.0 scfm (0.085N/m3) result in an exceptionally stable, fast responding controller. Relay is machined from diecast aluminum and has stainless steel inner valve parts and integral supply and output connections (1/4" FNPT). May be easily dismantled for cleaning without disturbing factory-set adjustments
Sensitivity
- less than one-tenth of full scale at 100% proportional band
Gauges
- Supply and output 30 psi for 3 - 15 psi (2,1 bar for 0,21 - 1,0 bar) valve operation
- 60 psi gauges for 6 - 30 (4,1 bar for 0,4 - 2,1)
- 100 psi gauges for 12 - 60 psi (6,9 bar for 0,8 - 4,1 bar) output
Accuracy
- indication, 1% in middle half of scale, 1-1/2% for balance of scale
Control Point Adjustment
- by means of knob inside case. Outside adjustment is optional
Proportional Band Adjustment
- with screwdriver
Unitized Construction
- each of the following units may be removed without disturbing other units: control chassis, complete or pre-calibrated range unit only – feedback unit only – nozzle and nozzle tub-ing only – complete relay unit, or supply gauge only, or nozzle feed orifice and cleaner assembly only, or relay bellows and valve stem and balls only – output gauge and tubing
Measuring Elements
- Pressure: basic element for ranges from 0 - 15 psi to 0 - 5000 psi (0 - 1,03 bar to 0 - 345 bar) consists of pre-calibrated Bourdon tube and movement with integral dial and pointers. Easily removed for repair or range change. Phosphor bronze standard; other metals available.
- Low Pressures: from 0 - 30" water to 0 - 15 psi (0 - 75 mbar to 0 - 1,03 bar) 316SS diaphragms
Features and Benefits
- The desired pressure or temperature control point is beyond the range of self-operated or pilot-operated valves
- Closer control is required than can be achieved with self-operated or piloted valves
- The process being controlled requires wide, proportional band, automatic reset, and/or derivative action
- The control instrument is mounted on a remote board
