Spring and diaphragm actuators
Spring and diaphragm actuators are rugged high thrust units with flanged yoke to bonnet connections for simple maintenance and better access to stem packing. These workhorses of our control valve lines have been proven and perfected for nearly forty years of in-service usage. They are available in four sizes: 35, 55, 85, and 135 in.
- Compact with strength for quick, accurate control
- Rugged cast iron or aluminum yoke with steel covers for long, trouble-free service

Levelmatic Liquid Level Pilot Controllers
Levelmatic pilot controllers use a simple, stable, floatless differential pressure sensing principle. They require only two simple connections to the vessel (open or closed). Standard units come in two sensing ranges: 0 to 36 inches and 0 to 200 inches(H20). Normal operating pressure is 10-22 psi. Static pressure on the sensing diaphragm can be anywhere within the range of 30″ Hg vacuum to 300 psig. Options include fixed or proportional band.
- 3 – 15 Psig Output
- Fixed or Proportional Band
- Bi-Metallic or Liquid Filled Temperature Element
- Single-Loop Pneumatic Controller
Differential Pressure Pilot UDDVP/UDRVP
UDDV, UDDVP, UDRVP pilot controllers consist of a differential super structure mounted on a standard force balance or adjustable band pilot body. Suitable for differential pressure control, vacuum control, pressure control with remote set point adjustments.
Two separate sensing diaphrams preventing contamination of either fluid in case of diaphram failure.
