Please let me know if <br /> there is anything else you require. <br /> Best regards, <br /> Mike <br /> Forward Header <br /> Subject: Re: 10 Series/Testing <br /> Author: Sean K Scott at OPW <br /> Date: 1/26199 1:42 PM <br /> Mike, <br /> I suggest only testing to 75 PSI (air pressure). This is 1.5 times <br /> our 50 PSI normal pressure rating. UL did test our 10 valve to 250 <br /> PSI for 1 minute without any problems. <br /> If you have any questions, let me know. <br /> Sean <br /> Reply Separator <br /> Subject: 10 eriesl Testing <br /> Author: Michael S.Wade at DPW <br /> Date- 1125199 3 1 3 PM <br /> Sean, <br /> An engineering firm-Tait and Associates, has advised that San <br /> Joaquin County plans to require hydrostatic testing of the product <br /> line, including shear valves at 300 psi- <br /> 1 advised that our 10 series valves should not be tested above 75 psi. <br /> Please advise what is the maximum pressure that the 10 series should <br /> be tested ? <br /> The 300 psi test came from AO Smith stating that their product could <br /> handle 200 psi, 1 112 times this is 300 psi. <br /> Thanks, <br /> Mike <br /> 1 <br />
