Model POSR-2

Description

The Model POSR-2 is a pilot operated regulator primarily for use with steam. The external pilot valve is supplied from a main valve body tapped connection. Sizes are 1/2", 3/4", 1", 1-1/4", 1-1/2", 2", 3" and 4" (DN15, 20, 25, 32, 40, 50, 80 and 100). Handles pressure drops up to 200 psi (13.8 Bar) with adjustable outlet pressures between 5 and 150 psig (.34 and 10.3 Barg).

Conexões finais

• NPT – Body sizes 1/2", 3/4", 1", 1-1/4", 1-1/2" and 2" F- to F- dim. per ISA S75.08.03
• Flangeado
  • DI Body: 125# FF/250# RF Integral – 1-1/2", 2", 3" and 4"
  • CS Body: 150# RF/300# RF Separable – 1", 1-1/2", 2", 3" Integral – 4"
• Ductile Iron material with NPT conn. meets dimensional requirements for ASME B16.4 for 250# pressure class. With 125# or 250# flange conn. meets dimensional requirements for ASME B16.1.
• Carbon Steel material meets ASME B16.34 for 150# or 300# pressure classes, and meets 300# pressure class for NPT conn.

Combinações de materiais: Corpo / Câmara da mola

• DI = Ductile Iron /
• CS = Carbon Steel
• CI = Cast Iron
• SST = aço inoxidável

Features

• Hardened Trim: Hardened pilot and main valve trim for long life.
• Bellows Seal: The pilot uses a bellows as a frictionless seal for the pilot valve plug. It was in corporated to ensure that the pilot maintains its sensitivity and smooth operation in older steam systems that are chemically treated and systems that are used intermittently. Prevents common “sticking” of pilot valve.
• Alta sensibilidade: Quatro molas de faixa piloto proporcionam alta sensibilidade e contribuem para a excelente estabilidade da válvula.
• Dois materiais de corpo: Ferro dúctil ou aço fundido.
• Fácil de instalar: Uma linha de detecção NPT de 1/4" (DN8) e o corpo da válvula são as únicas conexões necessárias.
