The Keystone 79U rack and pinion actuator has gained the reputation
has a heavy-duty rack and pinion that will take on conditions
that kill lesser competitors. The 79U is manufactured to mount
directly on the Tyco-quarter turn butterfly line eliminating
the need for external mounting kits. It is available in both
spring return and double-acting versions and comes standard
with ESPC powder coat over the hard anodized finish for extra corrosion
resistance.

Morin Scotch Yoke actuators have continued to gain market share
over the years due to the corrosive resistance material used
along with very high reliability. Morin offers the B series,
which incorporates ductile iron housing with stainless steel
cylinders as a standard. The S series is an all stainless steel
actuator that is priced to compete with most rack and pinion
and scotch yoke actuators. The HP takes the same proven technology
but adapts it for use with high-pressure hydraulics. Morin also
offers a complete line of accessories such as lockouts, ESD packages,
overrides, and mounting hardware.
- Canted Yoke models for torque seated valve requirements
- Pneumatic supply pressures: 160 psig
- Output torques: up to 240,000 in lbs
- Temperature range -22 to 212 °F
