The PCV regulators are constructed of aluminum and have a maximum supply pressure of 250 PSI (1724 kPa). These units come with a 35 micron filter and have a 0-125 PSI (0-862 kPa) regulated pressure range. The adjustment screw has a wrench knob with locking nut. The Williams pressure regulator also includes a 2” Wika pressure gauge with dual scale readings of both PSI and kPa increments, for a variety of applications.

The Williams “V” Series pneumatic metering pumps are engineered for PERFORMANCE, QUALITY, SAFETY and SIMPLICITY.

The WPC-9001 is an electronic control module designed to automate the speed control of Williams pneumatically operated metering pumps. The WPC-9001 interfaces with our pumps through the use of an electro-pneumatic solenoid valve. The solenoid valve is used in place of our Oscillamatic® controllers, where the speed is adjusted manually.

Simple design and ease of installation make setup quick and straightforward, while maintenance is minimal thanks to its robust, corrosion-resistant construction. Featuring all 316 stainless steel wetted parts, the pump stands up to the toughest environments with long-lasting performance.

The Cost Effective Simplicoty & Safety of a Pneumatic Metering Pump Design

The WILROY® is a hydraulically actuated diaphragm pump which delivers chemical containment, low maintenance, overpressurization protection with unsurpassed accuracy and repeatability. We invite you to look at how we can meet your chemical injection needs with proven solutions from Williams Milton Roy.

The APU pulses the 3-way solenoid valve which is connected to the pneumatic pump. The solenoid is cycled “on and off” to operate the pump. As the process signal increases or decreases, the pump cycles in direct proportion. Thereby increasing or decreasing the amount of chemical injected.

The MK XIIA combines the advantages of 316SS Stainless Steel construction for maximum corrosion resistance and the Diaphragm-Style design for minimal maintenance to provide for optimum performance
