Introduction

Replacing an installed Hirata Valve Industry cryogenic gate valve requires identification of the original valve configuration and the actual operating conditions.

Pressure class, nominal size, body material and external appearance alone are insufficient to confirm interchangeability. Hirata Valve Industry manufactures valves according to customer specifications; consequently, two visually similar valves may differ in dimensions, internal materials, sealing construction and temperature capability.

Hirata Valve Industry's cryogenic gate valve featuring an extended bonnet design, Class 150 pressure, nominal size 150A, crafted from durable SCS13A material.

Confirmed Manufacturer Scope:

The following information is confirmed at the Hirata Valve gate-valve product-family level. It does not define the specification of an individual installed valve.

Parameter	Confirmed Manufacturer Information
Manufacturer	Hirata Valve Industry Co., Ltd.
Product Category	Gate valve
Function	Full-open or full-closed flow isolation
Throttling Service	Not intended for intermediate-opening flow regulation
Low-Temperature Fields	Liquid hydrogen, liquid nitrogen and liquefied natural gas
Nominal Pressure Range	150LB to 2500LB; 10K to 63K
Nominal Size Range	15A to 1500A; 1/2B to 60B
Operation Methods	Manual, pneumatic, motorized and other configurations
Body Material Families	Carbon steel, stainless steel, cast iron and other materials
Manufacturing Basis	Manufactured according to customer specifications

Available size depends on pressure rating and the complete valve specification. The manufacturer’s published range does not confirm that every pressure, size, material and temperature combination is available.

Specification Boundary for the Illustrated Valve

The supplied images show an extended-bonnet cryogenic gate valve identified graphically as Class 150, 150A and SCS13A.

These values have not been verified against an official model-specific drawing, nameplate or manufacturer datasheet. They should therefore remain reference values until supported by original documentation.

The images must not be used as the sole technical basis for quotation, manufacturing or interchangeability approval.

Why Cryogenic Replacement Data Matters

Cryogenic service introduces technical requirements beyond nominal pressure and size. The valve configuration must be evaluated against the minimum operating temperature, fluid characteristics, thermal cycling and installation arrangement.

For an extended-bonnet valve, bonnet-extension dimensions and the location of the packing system may affect compatibility with existing insulation, cold-box interfaces and available operating space.

The following items can materially affect replacement suitability:

Minimum and maximum operating temperature
Design pressure and pressure-temperature rating
Exact cryogenic fluid and operating phase
Face-to-face and end-connection dimensions
Bonnet-extension length
Body, bonnet, stem, gate, seat and trim materials
Packing, gasket and sealing configuration
Flow direction and installation orientation
Manual or actuated operation
Applicable project and piping standards

A replacement should not be approved from the pressure class, nominal size and body material alone.

Service Life and Replacement Assessment

The official Hirata product information does not state one fixed service-life value for every cryogenic gate-valve configuration.

Actual service life depends on the original design, cryogenic fluid, operating temperature, pressure, thermal cycles, opening frequency and maintenance history.

For an installed valve, provide its manufacturing or installation year, estimated operating period, operating cycles, repair history, observed leakage and reason for replacement. This information helps determine whether the requirement concerns normal service-life replacement, process-related damage or changed operating conditions.

Manufacturer Verification and Japan Sourcing

Once sufficient documentation is available, Nichiboku can coordinate Japan-side identification and current supply-feasibility review.

Manufacturer confirmation may be required to establish whether the original configuration remains available or must be reviewed as a new made-to-order requirement. Submission of technical information does not automatically confirm availability or interchangeability.
