Features:
  • Permits the use of both hands during gauging or sampling
  • Ultra-tight sealing reduces product leakage and fugitive emissions
  • Designed for easy maintenance, thus reducing downtime and lowering operational cost
  • Gauge hatch is able to be mounted to 150# ASME flanges or DIN bolting
  • Incorporates a mechanical lock system to be used with a pad lock or lock out bar
  • Bonding straps are standard
  • Foot Pedal with serrated treadle surface to avoid foot slippage when opening.

 

Specifications:
  • Sizes: 4” (100 mm) to 10” (250 mm)
  • Material of Construction: Aluminum (Non-Sparking), Carbon Steel, Stainless Steel
  • Bolting: 150# ASME, PN 10 DIN, PN 10/16 DIN, PN 16 DIN, Un-drilled
  • Diaphragm: Buna-N (black), FKM (blue), or FEP (clear)

Blanket Gas Regulators, Model: 3000 Series

 

Description:

Blanket Gas Regulators from Groth Corporation ensure that a constant gas pressure is maintained in the vapor space of a storage tank. A blanket gas regulator supplies an inert gas to prevent a vacuum from developing when liquid is removed from a tank, to maintain the desired blanket pressure when the temperature drops, and to prevent outside air from contaminating the tank or creating a flammable or explosive environment. A blanket gas pressure as low as 0.5 InWC prevents outside air and moisture from entering the storage vessel and reduces evaporation of the stored product to a negligible amount. The end result: product conservation and significant reduction in tank emissions.

Groth blanket gas regulators provide a controlled gas environment in storage tanks for the following applications:

  • Refineries
  • Chemical & Petrochemical Plants
  • Liquid Bulk Storage Terminals
  • Pulp & Paper Plants
  • Food & Beverage Storage

 

Specifications:

• Simple operation, spring-loaded “push-push” balanced piston design
• Bubble-tight shut-off
• Variable orifice, field-adjustable flow capacity
• Single stage regulator
• Setting ranges from 0.5 InWC to 15 psig
• Modulating opening
• Minimal lockup and droop

Features:

• Grounding Cable connects the head and flange
• Cushioned Air pallet
• Peripheral Guiding

 

Specifications:
  • Size: 16″ (DN 400) , 20″ (DN 500) and 24″ (DN 600)
  • Material: Available in carbon steel, stainless steel, fiberglass and other materials
  • Pressure: 1.5 oz/in2 to 16 Osig (6.46 mbarg to 68.9 mbarg)
  • Certification: ATEX Approval
  • Manufactured in an ISO 9001 Certified Manufacturing Facility
