FOREWORD
Personal safety and Long Term Ownership of your DHV Rising Stem Ball Valve is the most important
matter in reviewing our Installation, Operation & Maintenance Manual. This manual will provide all
the necessary safety guidelines for our valve including information for the valve transportation,
storage, installation, operation and maintenance. Please read carefully before installing or servicing
the valve.
DHV provides general guidelines in this manual, and cannot provide specific data and warnings for all
possible applications. The purchaser/end user must therefore assume responsibility for proper valve
selection, sizing, installation, operation, and maintenance of DHV valve products. The purchaser/end
user should read and understand this document and any instructions provided with the product, and
conduct training with its employees and contractors to ensure they are aware of the proper and safe
use of DHV valve products in connection with the specific application.
1. ENDUSER INSTRUCTION
Personnel safety is always the most important factor in the transportation, storage, installation,
operation and maintenance of any valve. DHV valves are designed to meet the customer’s order
requirements and specifications. DHV disclaims all responsibility for problems that may be caused by
applications other than the specified use. Valve service pressure/temperature information is detailed
on the valve name plate. When selecting a valve, always consider the application, service and
temperature for the intended service. Select the applicable valve material for anti-corrosion and anti-
abrasive service. For safety of personnel and plant/environment: Prior to conducting any service to
the valve, ensure the valve is not under pressure, properly vented, and drained before servicing. For
all electric, hydraulic or pneumatic actuated valves, all power connections to the valve/actuator must
be turned off before performing any maintenance and service. When performing any operation,
maintenance or service, personal protective equipment should be used, such as protective clothing,
oxygen masks, safety glasses, work gloves, etc. DHV will not be responsible for any loss or expense
resulting from the failure of equipment, damage to any property, or death or injury to any person
resulting in whole or in part from repairs or modification performed by other than authorized DHV
personnel. Such unauthorized repairs shall also serve to terminate any contractual or other warranty,
if any, on the equipment and may result in equipment no longer meeting applicable requirements.
