1. NPS 2 / DN 50 body size spring range is limited to 45 psig / 3.1 bar.
2. Maximum setpoint is limited to 150 psig / 10.3 bar for constructions with Fluorocarbon (FKM) diaphragm.
Available in linear and quick opening trim cages for gas
and liquid applications, respectively. The cage-guided
metal plug provides superior control and stability.
The Type MR105 with steel or stainless steel body
construction has been designed to meet API 614 as
required by lube oil manufacturers.
Features
Travel Indicator—Travel indicator option provides
visual indication of the valve movement from the
closed to open position.
Large Flow—Able to pass large ow rates with
minimal offset from setpoint.
Stability—The Type MR105 regulator’s cage-guided
metal plug design provides superior control stability of
delivery pressure.
Fast Response—Direct-operated allows for fast
response to meet the most demanding pressure and
ow requirements.
Steel and Stainless Steel Constructions Meet
API 614 Requirements—Steel and Stainless steel
body constructions comply with the recommendations of
API Standard 614.
Available Constructions to Meet
NACE MR0175-2003 and NACE MR0103
Requirements for Sour Gas Service Capability—
Optional materials are available for applications
handling sour gases. These constructions comply
with the recommendations of NACE International
Standards MR0175 and MR0103.
Multiple Trim Materials Available—416, 316 and
316L Stainless steel options are available to meet
wider application requirements including demands on
lube oil and cooling water applications.
