Wm. W. Meyer & Sons, Inc. products

The HDX Heavy Duty Extra-Tough Drop-Thru rotary airlock valves are designed to withstand high temperatures and pressure differentials up to 22 psi. This legendary design sets the standard by which all others in the industry are measured. It offers the heaviest gauge rotor vane stock of any competing product, extra thick endplates, flanges and housing walls, along with outboard mounted oversized bearings that are prelubricated and permanently sealed to ensure low maintenance and prolonged life.

The HDBT Heavy Duty Blow-Thru rotary airlock valves are ideal for the Pneumatic Conveying of free-flowing material in food, grain, chemical, milling, baking, plastics and pharmaceutical applications. These units are uniquely designed to handle non-abrasive powders and where the product requires an assist in clearing the rotor vane pockets. The HDBT design is especially suited for low headroom installations and retrofit applications.

The HDSE Heavy Duty Side Entry Drop-Thru rotary airlock valves are designed for applications involving relatively large particles that cannot be reduced by the shearing action between the rotor blades and the housing at the inlet. They are also suitable for applications where small fines produced by the shearing action could cause damage to the system or create hazards. The built-in “V” shaped product inlet reduces the shearing to a single point virtually eliminating product degradation.

The Meyer HDXP Heavy-Duty, NFPA design valves are custom applied units to your specific application. Meyer engineers review the application and evaluate the design based on KST values for the material, temperature, pressure and ambient conditions. Units can be built in cast iron, stainless and cast steel to match the specific NFPA requirements. Special XP switches, controls and motors are also added as needed to match the installation environment. Each valve is uniquely built and documented. The Meyer HDXP is ideally suited for all your NFPA installations.

The Meyer W.E.A.R. (Wear Elimination & Abrasion Reduction) Valve provides the ultimate package for your abrasive material build up applications. The valve internals are coated with a variety of wear resistant coatings specifically matched for the materials conveyed. Housing coating options include Heavy Chrome, Diamond Chrome, Ceramic and Chrome Carbide along with all White Iron cast designs. The rotor is a closed end type and typically hard faced on all tip contact areas with Stellite and precision ground. The shaft packing area is purged through a lantern ring design for optimal life.

The FT Valve is designed for economical and reliable material metering and airlock service. The FT valve works beneath dust collectors, cyclone separators, and pneumatic conveyors where temperatures do not exceed 750°F and pressure differentials are less than 15 PSI.

Ideal for pollution control across many industries. The UDV Universal Duty Valve is designed for economical and reliable material metering and airlock service.

Direct Drives Provide one of the cleanest and most efficient ways to handle dry bulk material making direct drives ideal for Mining, Cement, Chemical, Food, Asphalt and Steel industries.

Meyer FV Fabricated rotary airlock valves are especially suited to handle large volumes of light to medium density products including large irregular material typically found in dust collection and low pressure pneumatic systems. These valves are available in carbon steel, stainless steel or abrasion resistant steel as an economical solution. The precision cut and welded valves feature flange type bearings, ribbed housing and headplates, with replaceable neoprene, viton or urethane sealstrips.

The CD Custom Design Series rotary airlock valves are a culmination of three generations of Meyer application expertise. These valves are designed to handle extreme operating conditions, unique customer needs or unusual installation requirements. Meyer sales engineers work directly with the customer to tailor a custom solution to their problem.
