ตัวแทนจำหน่าย Fisher by Emerson Type 99 Pressure Reducing Regulator ในประเทศไทย
The Fisher Type 99 is a pilot-operated pressure regulator designed for high-pressure gas systems in distribution, industrial, and commercial applications. It offers precise pressure control and supports demanding operations with high inlet pressures.
Features and Benefits of the Fisher Type 99 Regulator
Versatile Applications
• Suitable for a wide range of uses including natural gas distribution, industrial boiler and furnace supply, ovens, mixers, air service, oxygen and ammonia service, and large commercial buildings like malls and schools.
High Pressure Capability
• Handles inlet pressures up to 1000 psig / 69.0 bar when used with a Type 1301F pilot supply regulator and Type H110 relief valve.
Exceptional Accuracy
• Maintains consistent downstream pressure even under fluctuating flow rates and inlet conditions. Helps optimize system performance and may eliminate the need for pressure-compensating meters.
Zero Bleed to Atmosphere
• The regulator directs all pilot bleed flow to the downstream system, ensuring no gas is wasted or vented during normal operation or shutoff.
Enhanced Low Flow Control
• Offers excellent control across a wide flow range, with pressure settings from 2 in. w.c. to 100 psig / 5 mbar to 6.9 bar.
Flexible Configuration for Special Services
• The Type 61L and 61H pilots can be customized with special orifices and springs for fast-opening, fast-closing, or monitor regulator applications.
Quick and Responsive Pressure Control
• The actuator diaphragm quickly adjusts the main valve based on pressure changes, supported by the pilot for accurate final positioning—ideal for high-capacity systems.
Simplified Installation
• No external pilot supply line needed. Pilot supply is internally piped from the inlet, saving time and effort during setup.
Easy Maintenance
• Inspect or replace the valve disk and orifice without removing the regulator from the pipeline. The union nut design makes actuator and pilot removal simple and fast.
Tight Shutoff Capability
• A heavy-duty main spring and lever mechanism apply strong force to ensure reliable, leak-free shutoff.
Multiple Pilot Options Available
Choose from three pilot types to suit your application:
• Type 61L: For low-pressure applications (with LD and LE variants)
• Type 61H: For standard high pressure
• Type 61HP: For extra-high pressure needs
All pilot types are integrally mounted for compactness and ease of use.
