Barstock Valve & Manifold Catalog
Data sheets available in:
Domestic Version
Orifice Block Valves
Designed for compact, side-by-side mounting on standard orifice flanges, condensate chambers, mercury traps and seal traps.
Instrument Needle Valves
A complete line of valves, up to 1" in various end connections and materials for general process shutoff applications.
Primary/Gauge/Block & Bleed Valves
These valves combine the function of shutoff of process media and allow bleeding of pressure between process and instrument.
HexBlok Products
New! OS & Y and Screwed Bonnet Single Block, Block and Bleed, and Double Block and Bleed Flanged Instrument Isolation Valves.
HexBlok Ball Valve Products
Typically used on liquid hydrocarbon applications to minimize the size and weight of the pipe-valve assemblies associated with gauge pressure or analytical instrument.
Monoweld Products
Typically used on single or dual gauge pressure or analyzer installations to minimize the size and weight of the pipe-valve assemblies used for primary and/or secondary isolation, vent and calibration.
d
Monoflange Products
New! OS & Y and Screwed Bonnet Single Block, Block and Bleed, and Double Block and Bleed Flanged Instrument Isolation Valves.
Mono-Ball Valve
Design is used for direct shutoff of flow like any ball valve. The difference is the compact design and light weight..
Manifold Valves
A complete line of two, three and five valve manifolds for gage, static and differential pressure transmitter.
Condensate & Seal Pots
Purpose os to catch and hold condensate and foreign material. This prevents damage to the metering system and/or manifold.
Power Valves
The majority of Hex Valves are available to ANSI B31.1. Find out more about our Instrumentation Valves for the Power Industry.
Specialty Valves
Sample/Drain, High Temperature Valves and Gas Distribution Manifolds. Industry.
Isolation Rings
Isolates gauge or switch from solids in process flow to assure accurate pressure readings.
