• The standard model has an opening time of 26 seconds at  60 Hz or 32 seconds at 50 Hz. A fast-opening model is  available with timings of 13 seconds at 60 Hz or 16  seconds at 50 Hz. 

• Maximum closing time is one second, which meets code,  standard and insurer requirements. 

• Models available with damper shaft, with or without spring  return; shaft extends out both sides and rides in Teflon-like  Delrin bushings; used with standard 7616BR Damper  Crank Arm. 

• Red OPEN indicator attached to actuator stem shows  when valve is even slightly open; yellow SHUT indicator on  valve stem shows only when gas valve is fully closed. 

• Models available with adjustable max flow limit switch. 

• Ambient temperature rating is -40°F to +150°F (-40°C to  +66°C) for 60 Hz models and -10°F to +158°F (-23°C to  +70°C) for 50 Hz and 50/60 Hz models. 

• Valve and actuator combinations can be mounted in any  position, with the exception of the 220 to 240 Vac, 50/60 Hz  models, which are mounted vertically. 

• Models available with factory-installed single pole double  throw (spdt) field-adjustable Auxiliary Switch. Field-addable  Auxiliary Switch kits are also available. 

• Standard enclosure meets NEMA 1 (IP30) requirements;  models available with NEMA 4 (IP54) weatherproof  enclosure. 

• V4055D and high pressure V4055E with Proof-of-Closure  Switch and V5055/V5097C or E with valve seal overtravel  interlock (double seal) to meet specific code, standard and  insurer requirements. a VE5000 is a European manufactured and approved valve for  European use only.

APPLICATION 

The V4055 Gas Valve Actuator, in combination with a  VE5000a, V5055 or V5097 Gas Valve, controls the gas supply  to commercial and industrial burners. When replacing a V4034 with a V4055, the V5034 gas valve  must also be replaced with a V5055 or V5097 gas valve. 

FEATURES • The V4055 Actuator, when used with the VE5000a, V5097  or V5055 Valve, is rated for final safety shutoff service. • The V4055 Actuator can be used with the characterized  guide model of the V5055 or V5097 Gas Valve to enhance  lightoff smoothness.
