All Parker Autoclave Engineer’s needle valves are available with piston type pneumatic actuators. Six sizes of air actuators (light, mini-light, medium, heavy duty or extra heavy, single and double stage) are offered to meet the service requirements of Parker Autoclave Engineer’s Low, Medium and High Pressure needle valves. Both air-to-open (normally closed) and air-to-close (normally open) designs are included in the product line. Dual acting Air-to-Open & Close actuators are also available.

For most Parker Autoclave Engineers valve series there is a choice of two or more actuator designs. This provides the most efficient and economical pneumatic valve operation for any combination of process requirements and available air pressure.

Actuators are available for outdoor service. These operators provide corrosion resistant components and prevent the ingress of outside elements. Weatherproof or Explosionproof (CUL/ATEX) Limit Switch position indication is available upon request.

Features and Benefits:

• Fail Close (Air-to-Open) or Fail Open (Air-to-Close) with Spring Return
• Dual Acting (Air-to-Open & Close) actuators are available in all sizes except Mini-Light and Light. Note: Not Fail-Safe
• Piston actuator sizing incorporates maximum allowable air pressure of 100 psi
• Yoke design for separation of process and air pressure/allows for limit switch position indication
• Visual Valve Position Indicator as standard – Limit Switch options available
• Anodized Aluminum Housing (for corrosion and wear resistance)
• -20°F to 200°F (-29° to 93°C) ambient temperature range. (for operation below 30°F (-1°C) dry air must be used and heat tracing is recommended.)

The need to remotely control process flow electrically using high pressure multi-turn needle valves has long been sought. Pneumatic control of this type is an engineering challenge and cost prohibitive. Parker Autoclave Engineers solves these issues with our FRC line of electric actuators. When mated to our Regulating Stem Needle Valves and sent a 4-20mA signal, this actuated valve system provides precise control when needed and even provides enough torque to close the valve when not needed. This valve/actuator combination is capable of controlling Liquid or Gas flows.

The FRC Electric Actuator uses a 4-20mA input signal to turn the valve a programed amount of turns from fully closed to fully open (typically 5 turns) while also providing a position feedback using an independent 4-20mA signal. It is also capable of closing the valve completely when a 4mA signal is received. Should power be lost, the valve will freeze and “remember” it’s last position and will not need to be re-zeroed. The FRC actuator is designed to work with a number of Parker Autoclave Engineers Needle Valves from 1/8″ to 3/4″ tube sizes and up to 60,000 psi (4140 bar) using the Regulating Stem option – see individual valve brochures for Cv and Flow Curves.

Features and Benefits:

• Designed for Multi-turn Needle Valves, tubing/pipe sizes 1/8″ to 3/4″
• Precise, accurate control using Regulating Stem option
• Operational Temperature Range: -40° to 160°F (-40° to 70°C) – Valve temperature not to exceed 600°F
• Closing Torque capable of up to 60,000 psi (4140 bar) operation
• Weatherproof or Explosionproof (CSA approved Cls 1, Div 1 Grps B, C & D)
• Maximum Rotation Speed: FRC1 = 4 sec/turn, FRC2 = 15 sec/turn (5 turn open/close)
• Weatherproof Enclosure is supplied with TURCK 5 position cable connector and 20’ of cable

The Parker Autoclave Engineers Micro-Metering Flow Control Valves are designed for modulating flow or pressure control in industrial and research applications at temperatures of 600°F (315°C) or below. Using our standard Micro-Metering valves configured for many different pressures and tube connection sizes, these valves are capable of very fine flow control with pressures up to 60,000 psi using an electric, multi-turn microprocessor controlled actuator. The combination of these two precision, high quality components, provide a superior low flow, high pressure control valve for use with either liquid or gas.

Features:

• The microprocess controlled motor guarantees optimum voltage, currect and torque control when starting, running or stopping valve rotation. The microprocessor also assures accurate stem location and repeatability.
• Power Requirement: 24 VDC/50 Watt Minimum
• Control Input: 4-20 mA (200 ohm) or 0-10 VDC (18K ohm)
• Rotation Speed: 10 RPM (6 turn maximum)
• Operating Temperature: -20ºF (-30ºC) to 185ºF (85ºC)
• Two (2) foot lead cable supplied
• Anodized Aluminum Housing, Satin Anodized, IP65 (NEMA 4) Weatherproof

Note: Minimum Flow is factory set and occurs at “0” position. Do Not Operate the valve below the zero position or damage WILL result. (Valve is only for metering flow and cannot be used to shut OFF flow.)

High / Low Temperature Extended Stuffing Box:

Used in extreme temperature applications to move packing from flow stream with heatsink to moderate temperature.

-HT High Temperature (over 800°F (427°C))

-LT Low Temperature (under -100°F (-73°C))

NOTES:

• Not typically needed for 10V2/SW Series valves as temperature range does not exceed the barriers below, but option is available for consideration. (Parker Autoclave Engineers does not recommend compression sleeve connections below -100°F or above 650°F).
• HT option code includes Graphite (-GY) packing.
• LT option code includes 316 SS Trim material and PTFE packing.

Extended Stem Option:

Stem extenders are offered for High and Low temperature operation or to extend through panel or barricade.

To order valve with Stem Extender, add “ES-” and length (6″, 12″, 18″, 24″) to beginning of valve part number e.g. ES12-SW6071. Other lengths to special order.

To order Stem Extender only, provide valve model prefix e.g. ES12-SW6. Handle not included – use same provided with original valve.

Clam Shell Handle Lockout:

(order separately using part numbers shown below, padlock not included)

Clam Shell Handle locks are provided to lockout valves in open or closed position preventing unauthorized personnel from actuating valve during shutdown or emergency situations. This clamshell design is available in four (4) sizes dependent on handle length:

• P/N AE004855 – 1″ to 2.5″ handle length
• P/N 90088 – 2.5″ to 5.0″ handle length
• P/N 90194 – 6.5″ to 10″ handle length
• P/N AE004350 – 8″ to 13″ handle length
