safety valve installation matters<\/h2>\r\n        <p class=\"zobai-install-p\">\r\n          A safety valve is the final protection device against overpressure. Even when the valve is correctly sized\r\n          and tested, poor installation can still cause leakage, unstable opening, chatter, reduced relieving capacity,\r\n          excessive back pressure, unsafe discharge or difficult maintenance.\r\n        <\/p>\r\n        <p class=\"zobai-install-p\">\r\n          Installation should always be reviewed as part of the pressure relief system, not as a simple mechanical\r\n          connection. The valve, inlet pipe, outlet pipe, discharge location, supports, drains and accessibility all\r\n          affect the final performance.\r\n        <\/p>\r\n      <\/div>\r\n\r\n      <div class=\"zobai-install-warning\">\r\n        <strong>Important safety note:<\/strong> This guide is for general engineering reference only. Final installation\r\n        must follow the applicable code, project specification, manufacturer instruction, equipment design requirements\r\n        and local safety regulations.
