MODEL VCR – AUTOMATIC RECIPROCATING
MODEL VCR This model incorporates a 4-way Double Bleed Pilot Valve. By means of Built-in Bleeder Valves and internal Cam Bosses, this unit will automatically reciprocate as soon as air pressure is applied. Because of this, it is recommended that a shut-off valve be mounted in the inlet line. Due to internal construction and application requirements, there can be a loss of approximately 1/4” to 1/2” of stroke. Minimum stroke available is 1/2”.
