Stainless Steel Industrial Valves Manifolds

Stainless Steel Industrial Valves Manifolds

Product Introduction

Valve Manifold offer two mainline block valves and a double block and bleed valve for the equalizer line. The manifold is primarily intended for gas service and is used to connect differential pressure transmitters to system flow meters. Connections are 1/2" Female NPT on 2-1/8" (54mm) centers Standard feature include two 1/4" NPT static pressure connections on the instrument side and one 1/4" NPT vent connection from the bleed valve.

Advantages

1.instrument manifold are manufactured in accordance with ANSI B31.1, B31.3 and MSS-SP-105;

2.2-valve manifold are used with pressure gauges or pressure transmitters;

3.3-valve and 5-valve manifold are used with differential pressure transmitters;

4.Upper stem and lower stem design, Stem threads above packing protected from system media;

5.100% seal test under 10Mpa nitrogen before delivery;

5% seal teat under 1.5 times water pressure.

Features of 3-way valve manifold

1.Maximum working pressures:

Stainless steel: up to 6000 psig (414 bar)
Alloy C-276: up to 6000 psig (414 bar)
Alloy 400: up to 5000 psig (345 bar)

2.Working temperatures:
PTFE packing: -65 °F to 450°F (-54°C to 232°C)
Graphite packing: -65°°F to 1200°F (-54°C to 649°C)

3.Orifice: 0.157 in. (4.0 mm), CV: 0.35

4.Two-stem design: thread hardened upper stem and smooth surface hardened lower stem

5.Upper stem thread lubricant isolated from system media

6.Linearly instead of helical movement of the nonrotating lower stem, avoiding galling damage to the seat and tip, as well as reducing the total friction area between the packing and the lower stem

7.Safety back seating seals in fully open position

8.Steady and durable fastening of the handle by double lock-pins

9.Suitable for sour gas service; materials are selected inaccordance with NACE MR0175/ISO 15156

10.Every valve is 100% factory tested with nitrogen
