DOMUS Pressure Regulator

Product catalog summary
Introduction
The DOMUS pressure regulator, developed by Gascat, is designed for high-pressure applications requiring precise pressure regulation, achieving up to 1% accuracy and a lock-up of up to 10%. It supports pressure adjustments from 1 bar to 120 bar and is constructed from stainless steel, making it suitable for non-corrosive gases like Natural Gas, Nitrogen, Oxygen, and Hydrogen. Key applications include natural gas decompression stations, wellheads, virtual pipelines, industrial processes using high-pressure cylinders, and high-pressure test benches.

Main Features
The regulator includes a pilot for outlet pressure adjustment, a bleed valve for dome pressure relief, and is entirely constructed from stainless steel. It features a filter element for protecting the obturator and seat, and allows quick access for maintenance.

Working Principle
The DOMUS regulator operates by loading pressure in the diaphragm's upper chamber (dome). It can be supplied with a pilot for inlet pressures up to 100 bar, and with a pre-regulator for higher pressures. The pilot adjusts the outlet pressure using a regulating screw, and a bleed valve relieves excess pressure when necessary. The regulator maintains a closed position when there is no gas consumption, opening to allow gas flow when consumption occurs.

Component Material
The regulator is made from materials such as AISI 316 for the body and dome, AISI 420 for the seat, and Buna N for the diaphragm. The filtration degree is 50 microns.

Technical Data
Maximum inlet pressure is 250 bar, with an outlet pressure range of 1 to 80 bar and a temperature range of -30°C to +80°C. Various connection sizes and classes are available.

Sizing
Sizing is based on determining if the flow is critical or sub-critical, converting flow values for different gases, and ensuring the regulator's capacity is not exceeded by more than 90%. The Joule-Thomson effect should be considered for high differential pressure applications, recommending the use of a heater to prevent freezing.

Pilot Series G30F / G32F
These pilots have a simple construction with fewer internal parts, reducing maintenance time. They offer outlet pressure accuracy up to 2.5% and include an internal filter element to protect against particles.

Dimensions and Weights
Dimensions and weights are provided for different connection sizes, with detailed measurements for installation.

WORKING PRINCIPLE O regulador de pressão Domus Pilotado opera pelo princípio de carregamento de pressão na câmara superior do diafragma (domo). The pressure regulator Domus Piloted works by principle of pressure loading in the diaphragm upper chamber (domo). O regulador pode ser fornecido somente com piloto para pressões de entrada de até 100 bar e com pré-regulador e piloto para pressões superiores. O pré-regulador faz a primeira redução de pressão para o piloto. O piloto recebe do pré-regulador ou diretamente da linha sensora a montante pressão de entrada do processo. Descarrega na câmara superior...

£> GASCAT DIMENSIONAMENTO O dimensionamento do regulador Domus e feito com base nas consideragoes a seguir: • definir atraves das pressoes de entrada e saida se o fluxo do processo e critico ou sub-critico; • converter com base no fator de conversao o valor da vazao para fluidos diferentes de gas natural; • nao ultrapassar o limite de 90% da capacidade de vazao do regulador. E calculado utilizando-se a equagao abaixo, onde: Q = Vazao em Nm3/h; P1 = Pressao de entrada em bar absoluto; P2 = Pressao de saida em bar absoluto; KG = Coeficiente de vazao do regulador. Nota Importante: e importante lembrar...

DOMUS Pressure Regulator-7

Os pilotos modelos G-30F e G-32F têm construção bem simples e, portanto, poucas peças internas, o que reduz o tempo de manutenção e facilita o manuseio. A precisão de regulagem de pressão de saída pode atingir valores de até 2.5%. The pilot models G-30F and G-32F have a simple construction and, because of this, less internal parts what reduces the maintenance time and become easier the repair job. The outlet pressure accuracy in can achieve values up to 2.5%. Ambos os modelos possuem elemento filtrante interno para proteção do obturador e sede do piloto, retendo pequenas particulas presentes...
