| Model RR Manual
Reset Relief Valve Overview |
| The OTECO model RR manual
reset relief valve protects slush pumps
and mud manifolds while guaranteeing
greater safety in operation. The Model RR
relief valve automatically snaps to a
full open position when the predetermined
pressure is exceeded or can be manually
opened by simply pressing the manual
release button. The position of the
release button indicates at a glance
whether the valve is open or closed. The
model RR is designed with a pressure
setting indicator (available in metric
units) which can be adjusted to any
setting within the operating range by
simply turning a nut on the top of the
valve. |

| Model PRV
Pressure Relief Valve Overview |
 |
| |
| The OTECO Model
PRV Relief Valve helps ensure
protection for slush pumps,
manifolds, and other expensive
components used in drilling
operations. The model PRV relief
valve utilizes shear pins to
relieve overpressure during
drilling and other operations.
Hardened stainless steel stems
and stainless steel liner subs
provide improved corrosion
resistance resulting in higher
reliability and longer valve
life. And with the OTECO model
PRV pressure relief valve
replacing shear pins is fast and
easy because of its easily
removed safety cover. The OTECO
PRV is available in 2 in. low,
standard, and high pressure, as
well as 3 in. high pressure
models. |
