The Anatomy of Our Sampling Valves

BIAR sampling valves are made up of three components: the valve body, drive, and accessories.

The valve body is meticulously constructed in accordance with the Piping and Instrumentation Diagram (P & ID). Within this framework, we offer three drive options, all designed with a spring-to-close mechanism to enhance safety. Additionally, our product range encompasses two distinct categories of accessories, which include open-top receptacles and sample cylinders.

Valve Body

Material:

  • Various Stainless Steels (e.g., 316, 304L, A20 & higher-grade alloys), PFA lined, Monel, Hastelloy C, and Titanium

Size Range:

  • ¼” to 4” sizes with valve bodies in 6” and 8” sizes and larger sizes available on request

Key Feature:

  • Connection types include NPT, threaded, other connection types available on request
  • Raised Face (flange class of 150 and 300 pounds)

  • Pneumatic Actuator
BIAR Sampling System Drives
Name Advantages Disadvantages
Spring-to-Close Hand Lever
Spring-to-Close Hand Wheel
  • Safety (operator can’t leave valve open unintentionally)
  • Fewer Steps in Sampling Process
  • One Hand Movement to Open Valve
  • Integrated Locking Position
  • Operator must hold actuator open while taking a sample
Pneumatic Actuator
  • Ideal for Composite & Remote Sampling
  • Sampling Timeframe can be planned to schedule precise sample amount for deposit in receptacle
  • High System Cost when used with a Time Delay Unit

Adapters and sample receptacles

  • For exposure-free sampling and a hands-off approach, use our REVO-BOX
  • To reduce exposure risk with minimum handling, use our Safety Cabinet
  • For atmospheric-sensitive samples, use our Needle Adapters
  • To eliminate fuming during sampling and minimize necessary steps, use our Thread Adapter
  • To simplify bottle handling at your sample station, use our Bottle Support
