ตัวแทนจำหน่าย Fisher by Emerson 627 Series Commercial - Industrial Regulators ในประเทศไทย
The Fisher by Emerson 627 Series is a line of direct-operated pressure reducing regulators designed for both low and high-pressure gas systems. Suitable for use with natural gas, air, and other industrial gases, these regulators are built to perform efficiently across a wide range of applications.
Key Applications
• Farm tap installations
• Monitoring regulators
• Slam-shut applications
• High-pressure industrial regulation
• Regulator-relief valve systems
Features & Benefits
Integrated Relief Valve Functionality
• Models like 627R, 627LR, 627MR, and 627BMR include an internal relief valve, reducing the need for separate external relief devices—this means lower maintenance and equipment costs.
Reliable Safety Design
• Even in the event of disk or linkage failure, the pusher post and travel stop system ensures that the internal relief valve still operates.
Relief Operation Indicator
• A rubber cap on the vent assembly pops off when the internal relief valve activates, making it easy to identify past overpressure events.
Easy Maintenance
• Internal components can be replaced without removing the body from the pipeline. A two-bolt connection simplifies disassembly.
Flexible Installation Options
• The diaphragm case and body can be rotated in four directions to fit tight installation spaces. The regulator works effectively in any position, provided the vent is properly protected.
Expanded Application Range
• The 627 Series covers a broad range of configurations, including long-body options (matching the Type 630's face-to-face dimensions with NPT threads).
Tamper-Resistant Design
• Comes with a locknut and protective cap to prevent unauthorized adjustment of pressure settings.
Hydrogen-Compatible Construction
• Evaluated and tested for material compatibility and leakage resistance under hydrogen service. Select configurations are certified as Hydrogen Ready.
Broad Flow Capacity
• Multiple body and orifice sizes are available to meet various system flow requirements.
Balanced Trim Option for Enhanced Flow
• The Type 627BM features a balanced trim design, offering increased flow capacity and inlet pressure handling (up to 1000 psig / 69 barg).
Tight Shutoff Capability
• Uses flat-faced disks made of Nitrile (NBR), Nylon (PA), or Fluorocarbon (FKM) for bubble-tight shutoff.
Cold Weather Compatible
• Models built from Stainless Steel, LCC, or Aluminum are rated for extreme cold, down to -40°F / -40°C.
