Process Valves, Pumps & Compression

API 6D Pipeline Ball Valves for pipeline, gathering, station isolation and piggable full-bore oil and gas service, with RFQ fields covering nominal size, pressure class, full or reduced bore, end connection, body construction, material and trim, seat and seal system, fluid composition, design temperature, actuation, fire testing, fugitive-emission and sour-service requirements.

Small-bore forged valves for oil, gas and process piping, with published manufacturing ranges of DN10-DN80, Class 150-2500 and -196 to 800 degrees C.

API 610 Centrifugal Process Pumps for crude, hydrocarbon, produced-water and utility pumping in upstream and process facilities, with RFQ fields covering rated and normal flow, differential head, suction pressure, NPSH available, fluid properties, solids, vapor pressure, operating temperature, pump arrangement, metallurgy, mechanical seal plan, driver, utilities and site conditions.

Progressive Cavity Pumps for Oilfield Service for viscous crude, produced fluids, sludge, polymers and multiphase liquids where a low-shear positive-displacement pump is suitable, with RFQ fields covering required flow, differential pressure, viscosity curve, solids size and concentration, gas content, inlet pressure, temperature, stator elastomer compatibility, rotor material, speed, drive, seal, connections and installation orientation.

API 618 Reciprocating Gas Compressor Packages for natural-gas gathering, booster, vapor-recovery, fuel-gas and process-gas compression, with RFQ fields covering gas composition and molecular weight, suction and discharge pressure, temperature, required capacity, turndown, number of stages, cylinder lubrication, driver, speed, cooling, pulsation control, material compatibility, hazardous area and emissions requirements.

Needle Valves and Instrument Manifolds for instrument isolation, equalization, bleed, calibration and impulse-line service around pressure and differential-pressure instruments, with RFQ fields covering valve or manifold arrangement, port size and thread, pressure and temperature, flow coefficient or orifice, body and trim material, stem tip, packing, mounting pattern, sour service, fire safety and cleanliness requirements.

Disc springs for valve actuators, flange-bolt preload and high-temperature service, with published outside diameters from 6 to 534 mm and material-specific service to 700 degrees C.
