Process Valve & Instruments makes tough jobs easier for people involved with: Manufacturing – especially Original Equipment Manufacturers (OEMs), Pulp & Paper, Specialty Fabrication, Power Generation, Oil & Gas, Mining & Metals, Military / Military Support, Chemical Processing, Food & Beverage,
Aerospace, Hospitals and Municipalities by supplying them with quality products, knowledge, and experience in a timely manner.
We help them: maximize uptime, increase output, decrease operating costs, improve safety, reduce inventory with JIT deliveries, gain consistency, and add automation. We support Engineering, Management, Maintenance Repair & Operations, Purchasing, and anyone challenged to do more with less.
To control flow and pressure, valves are necessary. They come in various types to fit the application in which they operate. They include: ball valve, butterfly valve, plug valve, needle valve, diaphragm valve, pinch valve, gate valve, globe valve, check valve, sanitary valve, specialty valve, sampling valve, instrument valve, safety / pressure relief valves, diaphragm valve , solenoid valve, gauge valve, diverter valve, angle valve, steam valve, control valve, and many other valve types. We offer pressure ratings from vacuum to 30,000 PSI. Valves can be sized from 1/8” thru 24”, and fabricated up to 120”. Valve bodies can be in Stainless Steel, Brass, Carbon Steel, Hastelloy, Monel, etc.
Each valve type is suitable for specific functions. Deciding what type of valve to be used in each specific application should be done by an expert with knowledge and experience. The basic classes of valve functions are:
We can also offer custom valves that are designed and created to perform according to your specific application needs.
Pipe, hose or tube systems can be joined by various fittings. A fitting or adapter is used to join straight lengths of pipe, hose or tube, adapt to different sizes or forms and regulate (or measure) fluid flow. They can also manipulate the direction of how fluid or gas flows through the system. These separate parts and pieces join together to provide secure, leak-free connections between sections. These different pieces are joined by various fittings, like tube fittings, pipe fittings, unions, weld fittings, hose fittings, VCO fittings, couplings, JIC fittings, compression fittings, adaptors, ORFS fittings (also called O-ring face seal fittings), calibration fittings, compression fittings, CGA fittings, ISO fittings, MILSPEC fittings , instrumentation fittings, etc.
The fittings can be made of various materials, such as: Brass, Stainless Steel, Carbon Steel, Hastelloy, Monel, Inconel & other exotic metals as required.) Fittings can be sized from 1/16” to 2 1/2”. Fittings can operate in pressure ranges from vacuum to 10,000 PSI.
Some of the most common types of fittings are: Elbows, reducers, tees, couplings, unions, caps, crosses, plugs, swage nipples, adapters, bushings and flanges
In addition to fittings and valves, sometimes there are instruments in a system that serve various purposes. Some of the instruments we supply and help specify include: hand pumps, nitrogen source kits, manifolds, a Ralston Instruments laboratory grade pressure and temperature meter and calibration device, pressure gauges, vacuum gauges, differential gauges, test gauges, process gauges, analog gauges and digital gauges, thermometers & thermowells, industrial transducers & transmitters, regulators and pressure switches, level switches, temperature switches, position indicating switches, force sensors, etc.
Some of the most widely used instruments include:
The applications and functions of hoses and tubing cover a wide range. They are useful in different systems and structures to carry liquid, gas, slurry, etc. One advantage of hoses, that has made them popular in the process industry, is their flexibility, even the metal-based ones. This versatility accounts for the varied materials they are made of. You can find them in both non-metal-based materials, such as: nylon, rubber, thermoplastic, PVC, silicone, fluoropolymer, TPR (thermoplastic rubber), latex, nylon, polypropylene, and polyethylene, among others and metal-based materials such as stainless steel, copper, steel, brass, Hastelloy, aluminum, etc.
We supply most sizes, types, materials and thickness of any type of flexible hose and custom hose assemblies and represent a wide range of fittings, couplings, & adaptors. Custom hose assemblies include: flexible metal, rubber, PTFE, beverage – DEHP & BPA free, chemical transfer, Air / coolant / stripwound hose, composite assemblies (hydraulic, pneumatic, jacketed) & expansion joints.
For tubing, we offer: import tubing, source & specification controlled domestic tubing in 304 stainless steel & 316 stainless steel dual rated, seamless tubing & welded tubing, custom coil tube available in 20’ lengths. Tubing from 1/8” to 2” OD’s with a variety of wall thicknesses & pressure ratings, ASME & ASTM compliant.
Actuators are used to operate valves, dampers, fluid couplings, and other devices used in industrial process control. The industrial actuator can use air, hydraulic fluid, or electricity for motive power. These are referred to as pneumatic, electro-hydraulic, or electric actuators.
We supply almost any kind of actuation, including: manual, pneumatic, electric, hydraulic. 1/4 Turn, Multi-Turn, Linear, Rotary Vane. All sizes and torque outputs. On / off / jog or modulating, fail- open actuator, fail-closed actuator, fail-safe actuator, spring return actuator. In materials made from steel, aluminum, or corrosion resistant: composite, stainless & special coatings.
A valve positioner is a device mounted on the actuator that exerts or reduces air pressure as necessary to make sure the valve achieves the correct position. Positioners can be pneumatic, electro-pneumatic or digital. Positioners make sure the valve is in the position commanded by the process controller.
We supply all types of positioners, including: pneumatic, electro-pneumatic or digital.
Custom actuator assemblies are designed specifically for the customer’s needs. All components are meticulously chosen and assembled by our competent experts to meet the customer’s requirements. Whether operating pneumatically, electrically or hydraulically, we provide unmatched expertise assembling, stroking & calibrating actuated valves either on / off or modulating. Over 60 years in house experience assembling & testing valve packages.
