Model BR is available in five sizes from 3/8 in. to 2 in., and can handle materials from 20 °F to 400 °F with the appropriate body/spring chamber and trim material combinations. Cashco Inc.; 785-472-4461.

 

emerson

Mobile diagnostic software

ValveLink Mobile software has mobile management of control valves on a Foundation fieldbus network. It’s available on 475 Field Communicators, and offers an intuitive interface featuring large touchscreen icons. Intrinsically safe Field Communicators extend ValveLink Mobile advantages to hazardous areas where Fieldvue digital valve controllers are located. Emerson Process Management; 641-754-3011.

 

CMSX positioner

Linear and quarter turn

CMSX positioner is designed for economical analog control of linear and quarter-turn actuators. It has high- and low-flow versions, and users can drive the same CMSX positioner with 0-10V, 4-20mA or 0-20mA signals. It’s safe and energy-efficient, consuming no compressed air when idle. It’s available in a fail open/closed version and fail freeze. A 4-20mA feedback signal is available as a standard feature. Festo USA; 800-993-3786.

 

Nelprof valve sizing and selection software1

Sizing, selection software

Nelprof valve sizing and selection software is available free of charge, and helps users find the right Metso valves and automated assemblies. This new version assures faster and more accurate selection of the right valve configurations. It also enables selection of automated on-off and emergency valves in addition to control valves. There’s even a module for multi-phase flow sizing, noise and cavitation prediction analysis. Metso.

 

PVC and CPVC pressure regulating valves

PVC and CPVC for pressure regulation 

PVC and CPVC pressure-regulating valves (PRVs) feature compact size, modular design and chemical-resistant plastic construction with no exposed metal parts. Offered in two models, Pressure Reducing Type 582 valve for maintaining constant outlet pressure and Pressure Retaining Type 586 Valve for constant inlet pressure,  they’re available in sizes from 3/8 in. to 2 in. (DN 10 - DN 50). GF Piping Systems; 800-854-4090.

 

362 and 562 series brass and stainless steel spool valves

High-flow spool valves

362 and 562 series brass and stainless-steel spool valves in ¾-in. and 1-in. sizes feature high flow rates. 362 is a three-way valve for single-acting process valves, and 562 is a four-way spool valve designed for double-acting process valves. Features include dual-approved solenoid option with ATEX d and UL hazardous location approvals, low-temperature models rated at -40° C, and momentary manual override. Asco, an Emerson company; 800-972-2726.

 

CMA electric

New CMA actuator functions

CMA electric, continuously modulating valve actuators have new features for operating process control valves. CMA actuators can now be specified with increased functions, including local controls, LCD positional display and programmable, fail-to-position performance. They accommodate single-phase or DC input power, and are designed for quarter-turn, rotary or linear operation. Rotork Controls Inc.; 336-659-3400.

ControlAir Type 6500 aluminum and Type 6600 stainless steel large flow volume boosters

Large-flow volume boosters

Type-6500 aluminum and Type-6600 stainless-steel, large-flow volume boosters are reported to be compliant to IEC 61508 for a SIL 3 safety rating. These large-flow volume boosters are ideal for applications requiring high flow. This is becaue the greater air flow provided by the Type-6500/6600 units allows valves where they’re applied to actuate more rapidly. ControlAir Inc.; 603-886-9400 x128.

 

 

Trunnion Mounted ball valvesTrunnion mounted ball

Trunnion Mounted ball valves include 2 in. to 48  in. valves in ANSI Class 150-2500 RF and RTJ. They’re available in cast and forged construction, and many alloys including A216WCB, A352 LCB/LCC, CF8M, CF3M, Duplex and WC6. Automated valve packages include rack and pinion, heavy-duty Scotch yoke and electric actuators with pneumatic and electric accessories and custom control circuits. A-T Controls; 513-247-5465.

 

badgerTop-mount, smart positioner

Research Control SRD991 top-mount valve positioner mounts on top of a control valve with a rugged linear potentiometer. While most valve positioners are side-mounted, top-mounted SRD991 uses a linear connection that mitigates hysteresis between the positioner and actuator by feeding back the actual position of a valve actuator faster, more accurately and more consistently for improved flow control. Badger Meter; 877-243-1010.

 

FM approved FireChek thermal shutoffsFire safety shutoffs for pneumatics

FM-approved FireChek thermal shutoffs with resettable, shape-memory alloy can automatically shut down a pneumatic control system when a nearby fire occurs, or when ambient temperature reaches 135, 150, or 165 °F. The testability and resetability of FireChek makes it a preferred choice over emergency isolation valves that rely on metal alloy fusible links or plastic burn-through tubing. Assured Automation; 800-899-0553.

 

Clampseal fire safe globe valvesFire-safe globe valve

Clampseal fire-safe globe valves for refining and chemical plants are available in Y, angle and T-pattern configurations in ½-in. through 4-in. sizes, up to ASME 2500 pressure ratings, and with NPT, butt weld or socket-weld ends. Clampseal contains a mechanism that compensates for thermal expansion. This and other features enabke it to meet API fire-safe standards by high margins. Conval Inc.; 860-749-0761.
